Math
Recommendations

A list of mock contests that I’ve written for and mock contests that I personally recommend.

Evan Chen’s olympiad program, which recently has had an RPG component added to it! I’ve taken many pages out of his book for MAST.
Reflections
Contest Report for Summer MAT 2021 (TeX)
A report on the first year of the MAT, which ran online.
Notes
Linear Algebra
I am much more partial to edition 2 than edition 3 of Axler for some reason. Perhaps it is because it feels more concise, or there is less wanton “put everything in a box” formatting. But either way, anything that relies on Axler will be referencing ed. 2, not ed. 3.
Abstract Algebra
Formal Logic
Mostly based on CMU’s 21300 Basic Logic course.
Miscellaneous
A proof of the Principle of InclusionExclusion
These are notes from my Fall 2023 AIME class that I decided to publicly share.
