Do as many exam questions as possible. No joke, it works like magic. Just a couple every day and you should get through them in a year's time. Use flashcards for definitions only; flashcards for anything else is pointless (in my opinion). Use the mark scheme to mark your answers (don't cheat and be strict). You're probably gonna have to beg whoever's in charge of the submissions to put a higher grade on your application... but it's worth a shot! Also, that kinetic energy question seems to come up all the time. It's a really easy 5 marks to bag!
