10. Classification conventions

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).
