This book is an absolute must for anyone studying Human Biology on the AQA Syllabus. I did not realise I was capable of achieving so much until I bought this book and I strongly recommend it to anyone - each chapter explains the topics so clearly allowing you to achieve maximum marks as it has practice questions, diagrams and all you need to aid you in your learning. This book truly is the bible of biology and is so easy-to-understand - whether you are a strong or weak candidate in the subject, you really can excel with this book and become the very best - believe it or not, biology is actually understandable with this book and we can finally makes sense of respiration, digestion, synapses and all the rest of it! If there is one book you need to get, without a doubt it has to be this one.
