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 and reassurance. The books are deliberately short and unitimidating and 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 and 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.
