The Longman study guides are written and compiled by GCSE examiners for GCSE students and are designed as all-year-round course companions for revision. They are specifically based on the guidelines laid down by the new National Criteria. There is advice on how to cope with the requirements of continuous assessment and on planning and implementing an effective revision programme and preparing for final examinations. Throughout there are comments by the examiner on important points and at the end of each chapter there is a typical student's answer with examiner's comments on it. Each book includes a pull-out revision planner.
