Ik this is hella late but I’ve got end of years coming up soon too. If you’re doing essay based subjects then I’d recommend just doing tons of essays (timed ones too, I’m rlly bad with timings) even if it feels like torture. Blurting is great too. Ive got this weird method where I have key ideas on small pieces of paper (they kinda look like flash cards) and I would get a random card and say whatever I remember about it then I’d get another card and see if I can link them. With the cards I can also make mind map kinda things too. It’s really useful for me because it involves tons of methods!
I hope you did well on your exams!
