This series is aimed at less able students who simply want to pass their KS3 SATs but also those who could do even better given the right guidance & reassurance. The books are deliberately short & unitimidating & take KS3 students through basic concepts using Andrew Brodie's carefully planned step-by-step approach. Tricky topics are broken down into manageable stages with lots of worked examples to illustrate every stage. Providing re-assurance & giving students confidence is a key feature of this series. A pull-out answer section with accompanying explanations means that these books can be used equally well at home with individuals or in a school setting with groups of students.
