The SQA National 4 Physics course consists of three units of suggested content. The key areas of each unit are discussed in detail in this BrightRED Study Guide using explanations, pictures, diagrams, drawings and examples. Helpful hints are provided throughout the book in the Don't Forget features, while there are plenty of opportunities to practice your knowledge through Things To Do And Think About. Some of the skills you will be expected to demonstrate are also covered in the book. The book allows many opportunities to test yourself to check whether you have understood the ideas and explanations. Quick questions follow each key area to test your understanding and to let you practice some of the ideas and techniques. Extended questions feature at the end of each unit. These questions are designed to help you master the problem-solving techniques and skills. Answers to both the quick questions and extended questions are provided towards the end of the Study Guide.

Thirteen 5* reviews on Amazon.co.uk: "Bitesized information and examples. Bought this to give myself a refresher course to help my daughter. It explains everything for the level she is at and has examples and questions for you to work on with answers at the back to check your calculations. It also explains what is needed for each level at exams. My daughter will use this and hopefully so will her younger brother".
