If you just want physics as another a level to show u can actually do it, then just practice the calculations and the major stuff. Also I doubt u could get an A without understanding it all becuase they ask lots of diff questions which only make up a small amount of the paper, but learning the equations and main stuff get u a easy B, maybe an A
Does anyoune alse do OCR advancing physics? do you find it really hard to revise for? the book is so dull!
I got the feeling to actually have full understanding of everything would take great effort + desire to understand it, which I dont have, physics just an A level to me I wanna do fairly well on.
Anyway, good luck with today's "Field and Particle Pictures" exam everyone!
