First and foremost, I have recently completed A2 Biology and used this book throughout the course.
This book is officially endorsed by AQA for their new Biology specification. As the specification is new, there is limited literature available and this book seemed like a logical starting point because of its endorsement by the examination board. It contains a vast amount of information about each topic and contains bullet points at the start of each chapter addressing the learning objectives from the specification; in addition, the book contains a large number of summary questions and examination-style questions at the end of each topic.
However, the book has a couple of fundamental flaws:
1. Too much information. If you want brief, quick-fire points then look elsewhere. There is a lot of waffle that won't necessarily be tested in the exam (this was confirmed by an AQA examiner in a talk we received).
2. No answers to the examination-style questions. In my opinion, there's no point doing questions that you can't check whether you're right or not. If you want the answers to these, you're going to have to seek them out yourself by siphoning through past AQA exam papers.
Overall, the book is comprehensive and contains all of the information (perhaps too much) required for you to succeed but it could be vastly improved by incorporating the answers to the mock exam questions within the book.
