My daughter finds these books really useful - a great revision guide which compliments and summarises all that she has learnt in class. Concise, clear and easy to follow. The format is very easy to read yet contains a lot of information. I have also found them useful in helping me to understand the subjects she is studying. I purchased the same books for Biology and Chemistry and I would highly recommend them all.
I love these books. They are written succinctly with a twist of humour and important facts are coloured to make them stand out. Facts that have to be learned are made prominent with a humourous 'Learn this' tag to drive the point home! They make excellent reference books throughout GCSE coursework. We use them to help with homework all the time. A must have.
