In October 2018, I held my first IB revision session, for N18 students. However, I was 16 at the time, and very unexperienced, and it didn't turn out that great. So I thought, instead of lecturing, why not make a written guide instead? It's since turned into an informal guide to all of the IB Physics E&M topics that I've written in the same casual tone as my Discord explanations, in the hopes of making it more accessible and understandable to students.
