lol but there are literally already revision guides or notes you can find all online.
I personally didn’t make any notes for these subjects, just straight into flashcards. I’d like put the dates I revised each deck of cards on an excel spreadsheet. I know people are different though so experiment between online notes, online folders, separate notebooks or even try my method of jumping straight into flashcards.
Think about it. The revision guide is already notes so no point. You need to remember said thing.
