This series provides both student and teacher with comprehensive assistance with the GCSE OCR Graduated Assessment Syllabus (1662). Written in the style of the OCR examiners, every aspect of the syllabus is covered in detail. Focusing on GCSE mathematics, this textbook has parallel calculator and non-calculator exercises catering for the new non-calculator paper, a chapter on the OCR-marked coursework tasks, and chapters which specifically offer development of the topics with a "Using and applying maths" approach. Features of the book include key points at the end of each chapter that summarize essential learning points; examiner's tips; and helpful teachers' resources.
