1. Introduction

This document sets out the Examination Conventions for marking and classification in examinations in the Final Honour School of Mathematics and Philosophy Part C.

Examination conventions are the formal record of the specific assessment standards for the course or courses to which they apply. This document explains how your work will be marked and how these marks will be used to derive your final classification for Part C.

The formal procedures for the conduct of University examinations are
established by the University's Education Committee. The Proctors have responsibility for the conduct of examinations in accordance with those procedures. The Proctors may be consulted  by chairs of examiners, or by senior tutors on behalf of examination candidates in their college, on matters arising in the conduct of exams.

The examination conventions applying to  examinations in Mathematics and
Philosophy in any given academic year are reviewed in Michaelmas Term of
that year by the Joint Committee for Mathematics and Philosophy,
and must then be  approved by the Mathematical, Physical and Life Sciences Division, and by the Humanities Division, following consideration by the Mathematics Teaching Committee and by the Philosophy Undergraduate Studies Committee.

The Board of Examiners may only make deviations from these conventions in exceptional circumstances, subject to the direction of Mathematics Teaching Committee, Philosophy Undergraduate Studies Committee, and the Proctors. This document is in all ways subsidiary to the current:

  • Examination Regulations, in particular ``Regulations for the Honour School of Mathematics and Philosophy'' and ``Regulations for Philosophy in all Honour Schools including Philosophy''
  • Examinations and Assessment Framework

Further information set out for examiners can be found in the appendices of the Final Honour School of Mathematics - Part C examination conventions: https://www.maths.ox.ac.uk/members/students/undergraduate-courses/examinations-assessments/examination-conventions

2. Progression through University Examinations

To qualify for your BA or MMathPhil in Mathematics and Philosophy you must pass a First and Second Public Examination. The First Public Examination in Mathematics and Philosophy is currently called the Preliminary Examination and is taken at the end of the first year. You must pass the Preliminary Examination before you can be admitted to the Second Public Examination.

The Final Honour School comprises three parts. Mathematics & Philosophy candidates for both the BA and the MMathPhil take Part A at the end of the second year and Part B at the end of the third year.  There is no requirement of a minimum standard to be achieved in Part A before a candidate can proceed to Part B.  All candidates are classified on the basis of Parts A and B together.

Any candidate who wishes to leave at the end of their third year and who satisfies the Examiners may supplicate for a classified BA in Mathematics & Philosophy at the end of Part B with the classification they have received in Parts A and B together.  In order to proceed to Part C, a candidate must be awarded an Upper Second Class or higher, together with a weighted Part B average of 59.5 or higher.

Candidates for Part C receive a separate classification based on their USMs in the Part C examination. A candidate  achieving  Honours, that is, an average USM $\geqslant 40$, is permitted to supplicate for the degree of MMathPhil. A candidate who in Part C fails to achieve Honours (that is, any candidate whose average USM in Part C is less than 40) may supplicate for a BA with the classification obtained at the end of Part B.

Successful candidates may supplicate for one degree only - either a B.A. or an MMathPhil.  Whilst the MMathPhil is doubly classified a candidate will not be awarded both a BA degree and an MMathPhil degree, with the associated classifications.

3. Part C Assessment Units

Students are assessed on the equivalent of 8 units.

Mathematics Exams

C1.1-C2.2, C2.5, C2.7-C3.8, C3.10-C5.2, C5.5-C6.4, C7.4-C8.7
Each mathematics paper will examine one unit and will be of one hour and 45 minutes duration. Mathematics units will be assessed by a closed  book exam. These will consist of three questions, each worth 25 marks. You may submit answers to as many questions as you wish, but only the best two answers will count towards the final mark for the paper.

In all papers the questions set should, as a whole, be fairly spread across the syllabus.

Questions will be broadly similar in style to previous Part C questions, with an easy start examining material explicitly covered in the course, followed by a part which tests understanding. Each question will be set so that a sound student can produce a complete
answer within 35-40 minutes. 

Each question should be divided into two to four parts and an indication of the raw marks available for each part of each question should be given on the question paper.

Mini-projects C2.3, C2.6, C3.9, C5.4 and C6.5

The mini-projects have a weighting of one unit.  USM marks will be assigned to a mini-project with the same meaning as regards class boundaries as in the mathematics papers and with reference to the qualitative descriptor in Appendix 7.

COD Dissertation
Dissertations have a weighting of two units.  The word limit for COD dissertations is 7,500 words. 

USM marks will be assigned to extended essays with the same meaning as regards class boundaries as in the mathematics papers.  In arriving at these marks, the relative weights attached to content, and style and presentation  will be  75% and 25%, respectively.

Computer Science Department Units
Please see the Mathematics and Computer Science Part C examination conventions at https://courses.cs.ox.ac.uk/course/view.php?name=exams_info.

Philosophy Exams

In Philosophy the subjects shall be as specified in the Special Regulations for All Honour Schools Including Philosophy. With the exception of 199 (Thesis), 121 (Advanced Philosophy of Physics) and some special subjects under 198, each subject in Philosophy shall be examined by one 3-hour paper (which will contribute 75% towards the total mark for the subject) and one 5000-word extended essay (25% of the total mark).

4. Examination Conduct

Part C candidates will receive information from the examiners about the conduct of the examination they will be sitting in Trinity Term of this academic year.  Examiners' Notices to Candidates from last year, which show the sort of information that will be provided, can be found on the Mathematical Institute website at https://www.maths.ox.ac.uk/members/students/undergraduate-courses/examinations-assessments/examination-conventions, past notices will be superseded by this year's notices.

5. Penalties for Non-attendance

Rules governing non-attendance at examinations and any consequent penalties are set out in full in the Examination Regulations (Regulations for the Conduct of University Examinations, Part 14). If you are prevented by illness or other urgent cause from attending one of your examinations you should contact your college office or college tutor as soon as possible.

In cases where the Proctors do not believe there are satisfactory reasons for non-attendance or an application to the Proctors has not been submitted, this will result in failure of the whole of Part C. In such a case, the examiners will award a fail for each of the Part C assessments.

6. Penalties for Late Submission of coursework

The Examination Regulations stipulate specific dates for submission of coursework to the examiners, this includes the Part C dissertations, mini-projects and any coursework you need to complete if you take a course taught by another department.  Rules governing late submission and any consequent penalties are set out in full in the Examination Regulations (Regulations for the Conduct of University Examinations, Part 14).

If you will be prevented by illness or other urgent cause from submitting your coursework on time you should contact your college office or college tutor as soon as possible.  Your college is able to submit an application for an extension of time to the Proctors on your behalf. Students can also apply directly for an extension of 7 calendar days via Student Self Service. Applying for an extension via self-certification does not require the provision of independent evidence. Further information is available at https://www.ox.ac.uk/students/academic/exams/problems-completing-your-assessment.

The scale of penalties agreed by the board of examiners in relation to late submissions of assessed items, without an accepted reason, is set out below.

Lateness Penalty, % point reduction
Up to 4 hours 1%
4-24 hours 10%
24-48 hours 20%
48-72 hours 30%
72 hours - 14 days 35%
More than 14 days late Fail

Note: The penalty will be a percentage reduction of the maximum total mark available for the work. For example, if a 10% penalty is applied to an assessment given a USM out of 100 then 10 marks would be deducted. The final mark awarded after application of the penalty cannot be below 0.  

Failure to submit a required element of assessment, without an accepted reason, will result in the failure of the whole of Part C. In such a case, the examiners will award a fail for each of the Part C assessments.

7. Marking conventions

Examination scripts, theses, dissertations, and essays are marked by examiners and assessors.  Their marks result ultimately in a University Standardised Mark (USM), in the range from 0 to 100, for each script and submitted piece of work, which are then used in the process of classifying candidates.  USMs in the classification process are always whole numbers.

7.1. Plagiarism

You are reminded of the importance of avoiding any plagiarism, please see  http://www.ox.ac.uk/students/academic/guidance/skills/plagiarism for further guidance. Depending on their severity, cases of suspected plagiarism may be referred to the Proctors for investigation or may be dealt with by the board of examiners. If dealt with by the board of examiners as a case of poor academic practice, the examiners may deduct marks (for lack of adequate referencing, poor use of citation conventions etc) of up to 10% of the marks available for the assessment. Where the consequence of the marks deduction would result in both the failure of the assessment and of the programme, the case must be referred to the Proctors.

We will reserve the right to conduct follow-up viva voce exams to check candidates' understanding of the examined material, even where these are not currently specified in the Examination Regulations. 

7.2. The scale of USMs

In classified examinations the USM  on each individual script and submitted piece of work is correlated with classification bands as follows:

  • 70-100: First Class
  • 60-69: Upper Second Class
  • 50-59: Lower Second Class
  • 40-49: Third Class
  • 30-39: Pass
  • 0-29: Fail

8. How USMs are determined in Mathematics

The processes by which USMs on scripts and submitted pieces of work are arrived at are as follows:

Analysis of Marks

The Board of Examiners for Part C will assign USMs for each paper taken in Part C and may scale the raw marks to arrive at the USMs reported to candidates. 

The examiners may choose to scale marks where in their academic judgement:

  • a paper was more difficult or easier than in previous years, and/or
  • a paper has generated a spread of marks which are not a fair reflection of student performance on the University's standard scale for the expression of agreed final marks, i.e. the marks do not reflect the qualitative marks descriptors.

Such scaling is used to ensure that all papers are fairly and equally rewarded.

When scaling the raw marks on a paper the examiners will consider the following:

  • the relative difficulty of the paper compared to the other Part C papers;
  • the report submitted by the assessor who set and marked the paper.

Examiners will use their academic judgement to ensure that appropriate USMs are awarded and may use further statistics to check that the marks assigned fairly reflect the students' performances on a paper.  Examiners may also review a sample of papers either side of the classification borderlines to ensure that the outcome of scaling is consistent with the qualitative marks descriptors.

8.1. Marking of Mathematics Examinations

All mathematics  examinations are marked by a single assessor or examiner according to a pre-agreed mark scheme which is strictly adhered to.  The examination scripts are then checked by an independent checker to ensure that all work has been marked, and that the marks have been correctly totalled and recorded.

The Part C dissertations are independently double-marked, normally by the dissertation supervisor and one other assessor.  The two marks are then reconciled to give the overall mark awarded.  The reconciliation of marks is overseen by the examiners and follows the department's reconciliation procedure (see https://www.maths.ox.ac.uk/members/students/undergraduate-courses/teaching-and-learning/part-c-students/teaching-and-learning/dissertations).

Part C mini-projects are independently double-marked, normally by the course lecturer and one other assessor.  The two marks are then reconciled to give the overall mark awarded for the mini-project.  The reconciliation of marks follows the department's reconciliation procedure (see https://www.maths.ox.ac.uk/members/students/undergraduate-courses/teaching-and-learning/part-c-students/teaching-and-learning/dissertations) and is overseen by the examiners.  The exception to this is that mini-projects which have pre-agreed model solutions and marking scheme are marked by a single assessor.  The mini-projects are then checked by an independent checker to ensure that all work has been marked, and that the marks have been correctly totalled and recorded.  

Please see the qualitative descriptors of the bands of marks awarded to examination answers, mini-projects and dissertations.

Further information on the setting and marking of mathematics papers is given in the appendices to the Examination Conventions in Mathematics available online https://www.maths.ox.ac.uk/members/students/undergraduate-courses/examinations-assessments/examination-conventions

8.2. Marking Schemes and Model Solutions

Assessors setting questions are asked to provide complete model solutions indicating everything that a candidate would be expected to write to answer the question fully.  The model solutions and marking scheme need to be sufficiently clear and comprehensive to be meaningful to an external examiner.

The model solution for each question should be accompanied by a marking scheme out of 25.  The marking scheme should aim to ensure that the following qualitative criteria hold (see also the class descriptors given below):

20-25 marks A completely, or almost completely, correct answer, showing excellent understanding of the concepts and skill in carrying through the arguments and/or calculations; minor slips or omissions only.

13-19 marks  A good though not complete answer, showing understanding of the concepts and competence in handling the arguments and/or calculations. Such an answer might consist of an excellent answer to a substantial part of the question, or a good answer to the whole question which nevertheless shows some flaws in calculation or in understanding or in both.

7-12 marks Standard material has been substantially and correctly answered with some possible minor progress on to other parts of the question.

0-6 marks Some progress has been made with elementary, accessible material.

Assessors should classify the parts of each question under the headings: 

B1: bookwork material: explicitly seen before;
B2: routine material: easily synthesized from material explicitly seen before; 
S: similar to material seen before;
N: new rider, demanding good command of concepts and/or methods.

8.3. Dissertations

The examiners should pay careful attention to what candidates have been told about the assessment of these in the Examination Regulations and the Course Handbook.  All dissertations are independently marked by at least two assessors.  The examiner responsible for dissertations will oversee the reconciliation of marks, following the department's reconciliation procedure (https://www.maths.ox.ac.uk/members/students/undergraduate-courses/teaching-and-learning/part-c-students/teaching-and-learning/dissertations).  If reconciliation is not possible, an additional marker should be appointed.

Dissertations will be assessed with reference to the following qualitative descriptors.

For CD Dissertations

90-100 Work of potentially publishable standard, as evidenced by originality or insight. The work should show depth and accuracy, and should have a clear focus.  It is likely to go beyond the normal level for part C.  The standard one sees in winners of one of the examination prizes.
80-89 Work in this range will be at the level of a strong candidate for a DPhil applicant.  The project will be an easy choice as a winner of a college essay prize. It will have depth, accuracy and a clear focus. It will show a strong command of material at least at the level of part C.  It is likely to contain original material, which may take the form of new mathematical propositions, new examples, or new calculations, for example.
70-79 The work submitted is of a generally high order, with depth, clarity and accuracy, but may have minor errors in content and/or deficiencies in presentation. It may contain original material, at least in the sense of new examples or calculations.
60-69 The candidate shows a good grasp of their subject, but without the command and clarity required for first class marks. Presentation, referencing and bibliography should be good, and the mathematics should have no more than minor errors.
50-59 The work shows an adequate grasp of the subject, but is likely to be marred by having material at too low a level, by serious or frequent errors, a high proportion of indiscriminate information, or poor presentation and references.
40-49 The candidate shows reasonable understanding of parts of the basic material, but reveals an inadequate competence with others.  The material may be at too low a level.  There are likely to be high levels of error or irrelevance, muddled or superficial ideas, or very poor writing style. 
30-39 The candidate shows some limited grasp of at least part of the material.
0-29 Little evidence of understanding of the topic. The work is likely to show major misunderstanding and confusion.

For OD Dissertations
70-100 The candidate shows clear focus on the question, with precise and accurate details (mathematical and other), imaginative selection of examples and appropriate selection and quality (rather than quantity) of sources, and cogent argument, supported by evidence.

Within this band the following finer gradations may be helpful:
90-100 Work of publishable quality.
80-89 Demonstrates originality of content or insight.  Work at the upper end of this range could be publishable after minor improvements. Would be an appropriate entry for a national or university prize.
70-79 Work of high or very high quality, but perhaps lacking the originality that would be expected of publishable work. Might be a good candidate, for example, for a college prize.

60-69 Work that addresses the given topic, with solid command of factual content, reasonable range of examples and sources, coherent argument and analysis, and correct referencing and bibliography. (Essays at the lower end of this range may lack some of these qualities or show them only intermittently.)
50-59 Work with some use of facts, sources, and arguments, but marred by one of more of a failure to address the topic, serious or frequent errors of fact, a high proportion of indiscriminate information, speculation or unsupported argument, and incomplete or inaccurate referencing.
40-49 The candidate shows some knowledge of the topic but the work is marred by several of the following:- high levels of error or irrelevance, muddled or superficial ideas, incoherent or non-existent argument, incompetent use of sources, or very poor writing style.
30-39 The work demonstrates a little knowledge of the topic but no coherent argument.
0-29 The work demonstrates almost no knowledge of the topic.

8.4. Mini-Projects

Mini-projects will be assessed with reference to the following qualitative descriptors.

70-100 The candidate has demonstrated an excellent understanding of almost all of the material covered with a commensurate quality of presentation and has completed almost all of the assignment satisfactorily, further subdivided by:

90-100 The candidate has shown considerable originality and insight going well beyond the straightforward completion of the task set.

80-89 The work submitted shows a near-perfect completion of the task at hand, but does not meet the additional requirements above, or does but has some defects in presentation.

70-79 The work submitted is of a generally high order, but may have minor errors in content and/or deficiencies in presentation.


60-69 The candidate has demonstrated a good or very good understanding of much of the material, and has completed most of the assignment satisfactorily, without showing the level of excellence expected of the above USM range.

50-59 The candidate has demonstrated an adequate understanding of the material and an adequate ability to apply their understanding, without showing the level of understanding expected of the above USM range.

40-49 The work submitted, while sufficient in quantity, suffers from sufficient defects to show a lack of adequate understanding or ability to apply results.

30-39 The candidate, while attempting a significant part of the mini-project, has displayed a very limited knowledge or understanding at the level required.

0-29  The candidate has either attempted only a fragment of a mini-project or has shown an inadequate grasp of basic material.

8.5. Qualitative description of examination performance in Mathematics

The average USM ranges used in the classifications reflect the following general Qualitative Class Descriptors agreed by the Teaching Committee:

First Class: the candidate shows excellent skills in reasoning, deductive logic and problem-solving. They demonstrate an excellent knowledge of the material, and can use that in unfamiliar contexts.

Upper Second Class:the candidate shows good or very good skills in reasoning, deductive logic and problem-solving. They demonstrate a good or very good  knowledge of much of the material.

Lower Second Class: the candidate shows adequate basic skills in reasoning, deductive logic and problem-solving. They demonstrate a sound knowledge of much of the material.

Third Class: the candidate shows reasonable understanding of at least part of the basic material and some skills in reasoning, deductive logic and problem-solving.

Fail: little evidence of competence in the topics examined; the work is likely to show major misunderstanding and confusion, coupled with inaccurate calculations; the answers to questions attempted are likely to be fragmentary only.

[Note that the aggregation rules in some circumstances allow a stronger performance on some papers to compensate for a weaker performance on others.]

9. How USMs are determined in Philosophy

Marking of FHS Examinations in Philosophy

All Philosophy scripts and submitted work in Finals are marked independently by two markers.  The two markers discuss any difference between their marks, and endeavour to agree a mark.  Since USMs are always whole numbers, the agreed mark cannot in general be reached by `splitting the difference' between the two initial marks, e.g. two Philosophy markers whose marks for a given script are 67 and 68, cannot submit a mark of 67.5, but rather must determine an agreed mark that is either 67 or 68. A third marker marks the script or submitted work if the two original markers cannot agree a mark.

9.1. Qualitative description of examination performance in Philosophy

The standard of work for the various classes is specified in the following terms.

These terms employ positive criteria (marked by “+”) and negative criteria (marked by “-”) as a basis for assigning marks. Written work is taken to meet the criteria set out below if for the most part it satisfies the relevant descriptions. These descriptions are to be interpreted in light of what would be expected at the relevant undergraduate level rather than in absolute terms.

  • Class I 70-100
    • In order to encourage use of  a wider range of First Class marks, markers are asked to give First Class marks divisible by 3 as initial marks.  Agreed marks can be any marks within the First Class range, e.g. initial marks of 72 and 75 might result in an agreed mark of 74.

  • Class I 70-85 (NB: marks above 85 are not awarded for translation work)
    • Upper: 80-100:

+ a commentary displaying in-depth knowledge of the passage, excellent analysis and criticism of the argument(s), distinction(s), or concept(s) found in the passage, a lucid and concise account of the relation of the passage to the wider context, or/and the whole work, or/and the author's general thought, or/and some problem in modern philosophy.

Lower: 70-79

+ a commentary showing a good understanding of the immediate and wider context of the passage, lucid and concise analysis of the ideas and/or arguments involved, and clear and precise language.

  • Class II.1 60-69
    • Upper: 65-69

+ a commentary displaying a good understanding of the context and a clear and concise analysis of arguments, distinctions and/or concepts in the passage.
- limited command of some aspects of the passage, or context; minor lapses in the analysis of the argument, occasional unclarity in expression or use of concepts.

Lower: 60 to 64

+ a generally clear and satisfactory commentary, offering a mostly correct specification of the argumentative context and a reasonable analysis of the argument, distinction(s), or/and concepts of the passage.

  • Class III 40-49
    • + a commentary that contains evidence of some knowledge of relevant facts and analytical skill.
      - generally weak, with confused or little specification of the context, or discussion and criticism of the argument of the passage; some irrelevance; muddled and unclear language. This class does qualify for an Honours degree.
  • Pass 30-39
    • + some attempt to specify the argumentative context or/and content of the passage; occasionally relevant material.
      - extremely limited and inadequate commentary; comments largely (but not entirely) irrelevant.
  • Fail 0-29
    • Completely, or almost completely, irrelevant or ignorant commentary; nothing, or almost nothing, written.

NB: Candidates should note that one of the commonest reasons for commentaries receiving poor marks is irrelevance.

9.4. Short weight

If a candidate answers fewer than the required number of questions, the overall mark will be

(n/N)A

where A is the mean average of the marks assigned to attempted questions, n is the number of questions attempted, and N is the number of questions required.

9.5. Rubric failure

If a candidate fails to obey a rubric expressing a condition stipulated in the Examination Regulations, the examiners may reduce the overall mark. In cases where the maximum number of questions that may be attempted in a given section, or on a given author, is N, and the candidate answers more than N questions in that section, or on that author, only the highest-scoring N answers attempted in that section, or on that author, will contribute to the overall mark. 

10. Classification conventions

The classification conventions for Part C are in conformity with the stipulation that ``the highest honours can be obtained by excellence either in Mathematics or in Philosophy provided that adequate knowledge is shown in the other subject of the examination,''  (in ``Regulations for the Honour School of Mathematics and Philosophy'', Examination Regulations 2023.

10.1. Averages of marks

After marks for each examination script and submitted piece of work have been determined (in accordance with section 7 above), classifications in Part C are determined from each candidate's weighted overall average mark, and in the case of candidates offering options both in Mathematics and in Philosophy, possibly also, depending on the configuration of marks,  from their average mark in Mathematics and average mark in Philosophy, according to the Rules for Classification in section Rules for classification in Part C.

Candidates who offer options (ii) or (iii) among the following four options allowed in Part C will have Mathematics and Philosophy averages as well as an overall average: 

(i) Eight to ten units in Mathematics;

(ii) Six to Seven units in Mathematics and one unit in Philosophy;

(iii) Three to four units in Mathematics and two units in Philosophy;

(iv) Three units in Philosophy.

from the lists of units for Mathematics and for Philosophy.

Taking as a `unit of examination' the material examined in a three-hour exam or equivalent, options (i) and (iv)  both have the weight of 4 units of examination, as follows:  8 Mathematics units (although examined in \(8 \times 1 \frac{3}{4}\) hours) are the unit equivalent of 4 three-hour exams;  three Philosophy units in Part C are examined in 3 three-hour exams and three 5000 word essays (the M-level element of Philosophy in Part C); 3 \(\times\) 5000 words = 15000 words, which is the word limit of a Philosophy thesis in Honour Schools with Philosophy where the thesis takes the place of a subject examined by a three-hour exam.  The weight of option (ii) is 3 units of examination  in Maths and 1\(\frac{1}{3}\) units of examination in Philosophy, for a total of 4\(\frac{1}{3}\) units of examination.  The weight of option (iii) is 1\(\frac{ 1}{2}\) units of examination in Maths and 2\(\frac{2}{3}\) units of examination in Philosophy, for a total of 4\(\frac{1}{6}\) units of examination.  In these terms the weights of the mixed options (ii) and (iii) are slightly greater than the weights of the entirely Mathematics or entirely Philosophy options (i) and (iv).   At the same time, candidates offering options (ii) and (iii) have the possibility to obtain a First with an overall average mark that would not otherwise result in a First.

Please note that from 2016/17 Part B Maths exams have increased in length from 1.5 to 1.75 hours but their weighting has not changed. The additional exam length is meant to give more time to solve the problems; the exams have not increased in difficulty}

10.2. Decimal points and rounding of averaged marks in the determination of classification in Part C

 Averages of marks are calculated to two decimal points, which the examiners need in order to recognize candidates very close to a class borderline, in which case their marks profile needs to be given particular attention, and also for ranking candidates when awarding prizes.  However, at the stage of applying the classification rules to determine a candidate's classification from their average marks, the averages are then symmetrically rounded to a whole number, so that e.g. 69.50 is rounded to 70 (which, if this is as an overall average, gives that candidate a First), and 69.49 is rounded to 69 (in which case, unless Rules (2) or (3) for Part C classification applies, the candidate is classified II(i), but only in that case after the examiners have carefully gone over the candidate's marks, being so close to a borderline).

10.3. Rules for classification in Part C

Let \(M\) denote the average USM for Mathematics papers in Part C. Let \(P\) denote the average of the USMs in Philosophy in Part C. As stipulated  in section Averages of Marks above, for candidates offering option (ii) and (iii), the overall average \(A\) is calculated as follows:

(ii) \(A = (3M + 1 \frac{1}{3} P) / 4 \frac{1}{3}\)
(iii) \(A= (1 \frac{1}{2} M + 2 \frac{2}{3} P)/ 4 \frac{1}{6}\)

The quantities M, P and A are calculated according to the above formulae; the weightings used in the calculations for (ii) and (iii) are those used in a typical year, and have deliberately not been changed despite the reduction in the number of Mathematics papers as a consequence of the coronavirus pandemic. After these quantities have been symmetrically rounded to the nearest integer, as stipulated in section Decimal points and rounding of averaged marks in the determination of classification in Part C, classifications are determined by the following inequalities:

(1) No candidate will be given a classification lower than that implied by the weighted average of the USMs for their units  on the scale 70--100 First; 60--69, Upper Second; 50--59 Lower Second; 40--49 Third; 0--39 Fail.

(2)  a candidate who offers combination (ii) whose weighted overall average mark is \(\geqslant\) 67, and

  • whose weighted average mark in Mathematics is \(\geqslant\) 70, and
  • whose weighted average mark in Philosophy is \(\geqslant\) 60, and
  • 1/3 of their marks by weight in Mathematics are \(\geqslant\) 70, e.g. two Mathematics units are \(\geqslant 70\) or a double-unit Mathematics dissertation is \(\geqslant\) 70

will receive a First Class  classification.

(3) a candidate who offers combination (iii) whose weighted overall average mark is \(\geqslant\) 67, and

  • whose weighted average mark in Philosophy is \(\geqslant\) 70, and
  • whose weighted average mark in Mathematics is \(\geqslant\) 60

will receive a First Class  classification.

The same considerations as in (2) and (3) apply at the Upper Second/Lower Second borderline, i.e.

(4)  a candidate who offers combination (ii) whose weighted overall average mark is \(\geqslant\) 57, and

  • whose weighted average mark in Mathematics is \(\geqslant\) 60, and
  • whose weighted average mark in Philosophy is \(\geqslant\) 50, and
  • 1/3 of their marks by weight in Mathematics are \(\geqslant\) 60, e.g two Mathematics units are \(\geqslant 60\) or a double-unit Mathematics dissertation is \(\geqslant\) 60

will receive an Upper Second Class classification.

(5) a candidate who offers combination (iii) whose weighted overall average mark is \(\geqslant\) 57, and

  • whose weighted average mark in Philosophy is \(\geqslant\) 60, and
  • whose weighted average mark in Mathematics is \(\geqslant\) 50

will receive an Upper Second Class classification.

(6)  A candidate whose weighted average mark is \(< 50\) and \(\geq 40\) will be awarded a Third Class classification.

(7) A `Pass' will not be awarded for the M.Math.Phil. Candidates whose average USM is \(<\) 40 in Part C may supplicate for an honours B.A. in Mathematics and Philosophy with the classification they received for their performance in Parts A + B.

11. Resits

A candidate who fails to satisfy the examiners at Part C (\(AvUSM < 40\)) may retake Part C on at most one subsequent occasion. The Part C assessments would be retaken the following Trinity term.

12. Alternative Examination Arrangements and Mitigating Circumstances Notices to Examiners

A candidate in any University Examination with specific learning difficulties or disability/illness may apply through the Senior Tutor of their college for alternative examination arrangements relating to their condition.  Please see http://www.ox.ac.uk/students/academic/exams/arrangements for further information on the process.

Candidates who would like the examiners to be aware of any mitigating circumstances that may have affected their performance before or during an examination are advised to discuss their circumstances with their college and consult the Examination Regulations (Part 13). The candidate's college will submit the Mitigating Circumstances Notice to Examiners for forwarding to the relevant chair of examiners.

A candidate’s final outcome will first be considered using the classification rules/final outcome rules as described above in section 4. The exam board will then consider any further information they have on individual circumstances.

Where a candidate or candidates have made a submission, under Part 13 of the Regulations for Conduct of University Examinations, that unforeseen circumstances may have had an impact on their performance in an examination, a subset of the board (the ‘Mitigating Circumstances Panel’) will meet to discuss the individual applications and band the seriousness of each application on a scale of 1-3 with 1 indicating minor impact, 2 indicating moderate impact, and 3 indicating very serious impact. The Panel will evaluate, on the basis of the information provided to it, the relevance of the circumstances to examinations and assessment, and the strength of the evidence provided in support.  Examiners will also note whether all or a subset of papers were affected, being aware that it is possible for circumstances to have different levels of impact on different papers. The banding information will be used at the final board of examiners meeting to decide whether and how to adjust a candidate’s results. Further information on the procedure is provided in the Policy and Guidance for examiners, Annex C and information for students is provided at www.ox.ac.uk/students/academic/exams/guidance

13. Declared to have Deserved Honours (DDH)

Candidates who have indicated they wish to be considered for DDH will first be considered for a classified degree, taking into account any individual Mitigating Circumstances Notices to Examiners. If that is not possible and they meet the DDH eligibility criteria, they will be awarded DDH. Further details can be found here: https://www.ox.ac.uk/students/academic/declared-awards
