How to revise Watch
plenty of methods out there that you can do- you can see what works when you do mocks etc.
examples- flashcards, notes, videos, diagrams, past papers, tables, essay plans, practice questions, essays...
Mindmaps are good to summarise a topic and then id strongly advise to turn all the theory into action and smash a load of past paper questions that are from your exam board. I never did that when I was younger but now i do and i look back and question why i didnt! its honestly sooooo useful and the examiners can only come up with so many questions to ask about the same topic!
Hope that helps! x
