This was to be used for a teenager to practice and check the answers to the questions. Unfortunately the answers to all the questions are available in a separate booklet(this was stated on the back of the book but not on the book description on e-bay). If i had known this before buying i would not have purchased it as the book cannot now be used to check any questions done are correct. You are better off buying the Letts GCSE visual revision guide.Easily used with examples.
