How to read this courseNotation, shared pages and conventions
These notes introduce course-specific concepts. Probability and calculus already taught in Year 1 have one canonical page and are linked under Before you start rather than repeated. The course has one lecture in each of its seven teaching weeks, so each lecture number equals its week number; the weekly tutorial solutions belong to the same week. Concepts appear at their first introduction and are reused by links afterwards.
