I'm doing my mock physics 2 AQA GCSE in a week, and I know there are a lot of formulas on this paper. I'm wondering if anyone knows if I actually need to learn all these, or just some, or none. Will there be any formulas given in the questions on the paper? It'd be real helpful if anyone who's done this exam, or a similar one (AQA physics would be good) could give me at least a guess at how many I need to learn.
