I bought this book so that I could help my daughter with revision for her GCSE resit. Having passed other exams well, she proclaimed she couldn't do chemistry and the teacher didn't teach, he just made them copy stuff from the board. She initially got an E grade.
I am reasonablly well educated, but I have never studied chemistry, and my physics and biology o levels were back in, erm herm, 1984.
I spent 2 hours reading the relevant sections of this book for her exams, and then together we worked through the paper she had already sat, using the book as a guide. We got an A*!
Afterwards we each worked independently on other past papers - without the use of the book until we were marking and needed some clarification. 5 papers later and she had grades of 2xA*, 2xA and a B.
This book was invaluable. Ok so it does have a few naff features where the author is trying to 'get down with the kids' (my daughter's words) but it was all we used. She's sitting her resits tomorrow and then we'll be waiting for her result, but she's confident.
