I am a year 13 A Level student got all grades 7-9. I would say the best thing to do is make flash cards, flip through them and recite them as if you're teaching a class. Walking around whilst doing this really helped me idk why I think it might have been because it kind of set a rhythm that helped to set the information in my head better?? Also do lots of mind maps cuz they help with linking ideas together in your minddddd.
