AQA (A) Biology: Molecules, Cells and Systems (Collins Student Support Materials)

HOWEVER there are several mistakes that have come to my attention. For example the book proudly states that the resting potential is achieved by more potassium ion moving out than sodium ions moving in. This is of course WRONG as the resting potential is achieved by more SODIUM ions moving OUT than POTASSIUM ions moving IN!

For this alone I am giving this book 3 stars.

My result for this unit was 88/90 and I based my revision around this book. I recommend using it in conjunction with a more detailed textbook, Longmans AS biology perhaps. This book and the others in the series are a must for this course though - buy it, you'll do well!

This book is amazing. I did the AQA syllabus for my Biology A Level, and I used this book and this book alone to revise for my exam (no notes, no big textbook, nothing else) and I got 94% for the module.

The only trick to this book is that every sentence is something you need to know and memorise - whereas in the main book, there is lots of unnecessary background information that you can ignore or forget. I found this particularly useful - you don't waste time revising things that you're not sure you need to know or not from the main book. This doesn't mean that the revision book is hard to understand, either; everything is explained very clearly and in the unlikely event you do get stuck, you can always consult the main course textbook. If you memorise all the material in this book you are guaranteed a (very high) A grade - it misses nothing out.

I'd also strongly recommend getting the revision books for the other modules, like I said, I only used the revision books to revise (with the exception of the last optional module that didn't have a revision book) and I got high As in all modules. Originally I didn't feel they were that important, so did the first module just from the main book - I got a C first time around, then for my resit bought the revision book and got the A. For the sake of five pounds it's really, really worth getting these books, I can't stress how good they are.
