very informative and detailed and since it came from the examining board itself it has the exact things you need to learn. Furthermore, after every page there are questions to test your knowledge of a specific topic you have learnt
However, if you want a cheap less detailed but good guide get a CGP book.
Delivered on time and as described - very pleased. Teaching science after a 10 year gap so hoping this book will bring me up to date!? Excellent illustrations and very clear text,lots of questions for students,learning outcomes clearly stated.
