What to buy

All you need are the relevant text books and revise guides. Many students don't buy their own text books and rely on revise guides; I suggest this is a false economy!

My favourite revise guides are published by Letts Educational. You can find them at W.H.Smiths and all good bookstores.

Text Books: Some exam boards recommend books, some don't. Here's the information that I've found out:

AQA
AQA have done a deal with the publisher Nelson Thorne who have produced materials designed around the particular AQA syllabuses. That doesn't mean that other publishers aren't producing relevant products, but you might as well get the ones they recommend. Here's the list with ISBN numbers:

Edexcel

Edexcel don't appear to have done a special deal with a particular publisher, but they do endorse many products. Those from Hodder Murray are mentioned, so here are the details of their products:

OCR

OCR say that they don't recommend particular text books, but point out relevant publishers:

For the Gateway Science syllabuses Collins and Heinemann
For the Twenty First Century Science syllabuses Oxford University Press
