This work features essential knowledge distilled from the textbooks into sharply guided exam-focussed revision. A checklist at the beginning of each chapter clearly lists what students need to know and breaks revision down into manageable chunks. Clean, well-spaced design makes content accessible and revision less daunting! It includes pre-tests, exam questions, sample answers, comments and advice from examiners. References to the Students' Book throughout the Guide show students exactly which units may need to be re-visited. Bump-Up Your Grade feature offers students essential advice from experienced examiners on how they can reach their full potential and achieve better results. The Revision Guides are linked to the Online Test and Assessment Service - at regular intervals students are prompted to go online, practice additional Revision Quizzes and view Model Answers.
