CGP produce excellent revision guides at all levels. They are quite expensive, so it's best to try and get them on eBay if you need them for multiple subjects, like me.
I got this as it was a lot cheaper than the exam board specific guides, it does have the same content. It has everything you need to know- if you can be bothered sorting through the other exam board's stuff, to find your specification's content. The book does have this at the top of each page, but you can't just read it through. Probably best for looking up particular things, not last minute cramming.
good for revision and quick reference
