Being an A2 Biology student I have found the book to be the most helpful and very informative. It has all the relevant information and the sections are clear and it is very easy to find things as it is well set out. The pictures are clear with diagrams well labelled.

Overall the book is very easy to understand, colourful and a great help. Show Less
