For chemistry and biology, make notes using a revision guide once, then do every past paper you can find. Don't go over the content again and again cause you wont learn it any better, the only way to improve your understanding is to do different questions on it.
For maths just do past papers, don't worry about notes But again mainly just do past papers. That's pretty much all you need for any A level.
