Complete Mathematics for GCSE by David Rayner
Written by an experienced teacher and examiner, "Complete Mathematics for GCSE and Standard Grade" is an ideal book for average-ability students. Groundwork is covered in the first section and then thoroughly revised in the second section before harder topics are approached. Its key points include: carefully graded practice questions to consolidate basic techniques, problems and investigations to develop skills required for coursework, emphasis on everyday situations relevant to the demands of future employment, and complete set of answers.
