A worry for all book buyers, this book is the correct book for the AQA A2 Biology exam and exactly the same one as was in my school.
There doesn't seem much point in reviewing this book, because, quite frankly, if your are doing the AQA exam, you simply have no choice in the matter. I would strongly discourage buying any other book without reading this one. The questions and syllabusss featured in this book are exactly what will appear in the exam. This is very important when it comes to specific figures such as in the PCR (polymerase chain reaction) temperatures as well as correct terminology of enzymes and processes (e.g. the exact sequence, and enzymes, involved in the transcription and translation of DNA).
The book doesn't come with the answers for the exam style questions but my teacher had this so it wasn't a problem. However there is a whole plethora of questions on virtually every page which do have answers in the back of the book. In my case i found these questions tedious but it was worth the effort doing some of the more tricky questions as revision.
All in all the book is essential if you are doing this exam. I used this book exclusively to both study and revise from and i managed to get an A* overall this June. Of course people are different and hard work is key, but without this book I struggle to see how anyone will be able to achieve a high grade.
