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 some recent exam papers. (Both 2024 and 2026 include a question on reversibility.) Further revision materials may be added later in the year. 

(a): 2026 exam paper. Solutions available.

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

(c): 2024 exam paper. Solutions available.
