Search up the specification. It will tell you all the stuff . From what I know there is 3 2 hour exams and the end of year 13 and that it starts off with some thing called the particle zoo. I'm doing physics aswell btw! What did you get at gcse?
i wasnt originally going to do physics because i didnt think i was gonna do that well but i ended up getting a 7 which i was so pleased with because i dont go to a very good school and a 7 was the highest anyone got in physics
