Each book covers one syllabus unit (except P2 and P3 which are covered in a combined volume). The syllabus content is arranged in chapters to provide a viable teaching course. Each chapter starts with a list of learning objectives. Mathematical concepts, terminology and notation are explained clearly and carefully. Key results and procedures appear in boxes for easy reference. Stimulating worked examples take a stepby- step approach to problem solving and there are plenty of exercises throughout, as well as revision exercises and practice exam papers.
