Everyone has their own way of revising. Some use flow diagrams or minds maps, some prefer revision cards, and some really learn from working through a revision guide. If you, like me learn best from this, this bok is fantastic.
Each topic is a chapter, and it guides you through with diagrams and bright clours, which makes it very readable. It says that at the end of each page you should write down what you have learnt from this page, and at the end of every chapter there's some revision questions and some practise exam questions. Used properly, this book leads you into the exam properly prepared.
I have the CGP books for Physics, Chemistry, Biology, Maths, French and Geography and I think they're brilliant
