This manual is designed to help students master the knowledge required for AS and A Level Physics, and to test their understanding throughout the course and while preparing for examinations. The text is divided into about 45 topics, each of which contains notes on the key concepts, graded questions and full answers. The initial questions are designed to build the student's confidence, and there are also questions that reflect the demands of AS and A Level. The full answers, including the steps involved in mathematical calculations, allow students to test their knowledge, to see where they have gone wrong, and to learn from any mistakes. The final topic deals with synoptic questions and how to answer them.
