Presentation: EXCELLENT, this is a very nice, colorful book. Chapters are clearly divided up, and each spread of 2 pages aims to cover one aspect of each chapter. The book is very well structured and has exam practice questions after each section, as well as questions on each page, aimed at getting you to think a bit further.
Content: Brilliant! Has everything required for, i would say, all alevel courses. If youre following AQA, then it even covers every one of the possible options unit at A2. Explanations are clear and very detailed, giving you more of an understanding than just knowledge. Each little section of each chapter starts with an introduction, putting into perspective why the information contained is relevant.
My only complaints: i find certain concepts difficult to get my head round, and 90% of the time this book really helps. It's just occasionaly ive been taught something, not understood it, read my book, still not understood it. That said, everyone understands things in different ways and perhaps i just didnt twig? Also, while certain sections go into immense, rich detail, others shy off a little- only really the explaination of how a nerve impulse works and the minute details of respiration.
OVERALL: excelent book, worth the money, great study aid- is NOT a textbook like the ones you get in school- this book could much more easily be used for self-study!! buy it!
