CP3: Problem Sheets for MT-26 (these are in fact from MT-22 and may be updated in real time)
CP3: Andre Lukas's Problem Sets for V&M (this is the MT-17 version; your current lecturer is using the same problem sets, and so shall we)
CP3: My 2021-22 Lecture Notes and Problem Sets on ODEs (I expect you to read these)
Pre-2013 Merton Maths questions (some of these can be used for revision)

My Lecture Notes on Dimensional Analysis (2011)
Richard Fern's typed, improved version of these notes (2015)

A1: Problem Sheets on Thermodynamics for MT-24 (these are in fact from MT-24 and may be updated in real time)
A1: Julien Devriendt's Lecture Notes on Thermodynamics (from our course some years ago, a good, tight read!)
A1: My Lecture Notes on Kinetic Theory and Statistical Mechanics for 2nd year (updated in real time, check back!)

If you would like to try your hand at more advanced material (or just extra material), the following two books proved a great success in David Hosking's lockdown tutorials with 2nd years in TT-20 (if you want a copy, drop me a line):

If any of the 2nd years are sufficiently fascinated by Kinetic Theory to want to study ahead, and at a higher level, you are welcome to attend the MMathPhys Kinetic Theory course. It is a 4th-year course, but the only "advanced" maths it uses are Laplace and Fourier transforms, so if you have done SO-1 you should be fine (although the pace might be quite brisk and you might encounter some allusions to as yet unfamiliar physics material, so if it proves inaccessible, just drop it).
