This book has been specifically written for the new two-tier Edexcel linear GCSE specification for first examination in 2008 by the highly successful Framework Maths author team. The book is targeted at the B to A* grade range in the Higher tier GCSE, and it comprises units organised clearly into inspiring full-colour spreads. Each unit offers: *Prior learning assessed at the start so students are fully prepared for the topic *Learning objectives identified so it is clear what students need to know *Clear explanations with examples showing the key techniques *Plenty of practice with clearly differentiated questions pitched at an appropriate level *Summaries and past Edexcel questions to help students gain responsibility for their learning It forms part of a series of four student books at GCSE, in which the other three books cater for grade ranges G to E, E to C and D to B.
