This book / cd rom was fab. Covers all the study material with revision questions every couple of pages, which help to focus and break it up. There are pictures demonstrating some of the facts, making them more digestible and more memorable. Has great test questions at the back, and the cd rom material is FANTASIC - I read the study material, did some of the written practice tests, and then went onto the cd-rom, which helped to reinforce what I did and didn't know, making me more confident, and also more aware of where I needed to focus my time. Also made it fun! Particularly useful is that you can tailor the cd-rom test material to make it focus on certain sections in the book, and when you get answers wrong it gives you a detailed output of the correct answer, and where in the book to read about it. I thought the book was perfect, it even made it fun, and I passed my test easily today, so it must have done something right!
