A revision guide which is both comprehensive and so well-written that children actually enjoy using it. I'm a big fan of the CGP study guide series, and the KS 2 Science Study book is no exception. The children of the household have worked their way through it without complaint ("I think it's good" - genuine feedback) and the colourful, well-designed pages and humour are about as far from a dusty textbook as you can get. We've also bought the KS 3 Science Revision Guide and associated work books and SATs practice papers. That's how good they are.
