For each topic in the AQA exam specification, there is an 'input' spread, which summarises the key points of this topic and gives hints for the exam, and an 'output' spread, of exam questions on this topic, for the student to practise on. In this work, answers are provided at the back, with a commentary and advice. For each section, a model answer is provided, at Grade A and at Grade C, with the differences between them highlighted, to help ensure that your students fully understand how they can improve their grades. Key features include advice and tips from examiners, worked examples, and quick tests as well as fuller exam questions, so every aspect of revision and exam preparation is covered. Each book has a gate fold cover, with detachable Revision Cards to aid learning. Each book has a detachable Revision Calendar. They are an ideal companion for the 'for You' series, but can be used with any GCSE Science scheme, to help achievement of higher grades.
