Revision materials

A couple of things to note about past exam papers:

- there was a slight change to the syllabus, starting with the 2024 paper. Poisson processes are no longer covered, and there is new material on reversibility.

- the papers from 2020 and 2021 had a different style since they were taken under open-book conditions. 

Here are four practice exam papers, involving closed-book-suitable questions from previous years that don't involve Poisson processes, and including a couple of questions involving reversibility. 

Solutions to two of the papers will be available for students to download.

(a) 2025 exam paper (with hint added to Q2(c)(ii)). 

(b): 2024 exam paper. Solutions available.

(c): Practice paper 1. Q1 (edited) from 2018, Q2 from 2022, Q2 from 2016. Solutions available.

(d): Practice paper 2. 2016 Q1, 2015 Q3, and a new question.

Of course many other questions from previous years are also suitable! Just avoid any material on Poisson processes if you want to stick to this year's syllabus.
