I bought the IGCSE Maths Edexcel revision guide (Richard Parsons) for my daughter who is currently sitting her IGCSE exams. She says that it was very useful - most definitely helped her (& she's an A* student!) She did not like the jokes - felt that the author was going about trying to make Maths funny in the wrong way; & was not succeeding. My daughter says that she would definitely buy it again (if need be, 'cause we do have it now) and would certainly recommend it to others to buy.
