Issues organising notes

Hi! I've just finished my a levels and yes, humanities notes are endless lol! The way I organised mine was in a big lever arch folder for each subject witch dividers splitting up things like notes, revision resources, past paper practice, essays etc. I then took a smaller folder into school with just the relevant sheets and a Polly pocket in it to store new sheets to file away when I got home. I hope that helps and good luck! Try to stay on top of it and keep your notes organised to make your life easier, but above all else look after your mental health!

My school uses a lot of digital notes + pdfs... are there any apps/websites you could recommend to keep track of notes and flashcards at the same time? Does anyone else have this issue?
