I'm in year 11 about to enter year 12 trying to learn ahead for physics and extension 2. Physics: because if I'm being honest I find my teacher's style of teaching to really not suit me so I find it easier to learn it by myself. And extension 2 because I've heard about how hard it is. I was wondering how I should learn ahead? Should I use the same textbook the school is using for maths, or a different one? Any tips or strategies for learning ahead? Any advice would be really helpful, thanks!
