This book is designed especially for the Cambridge system, to meet the requirements of the latest mathematical syllabus for Edexcel, GCSE, IGCSE and O-Level Mathematics. The topics throughout the book are carefully graded/organized according to the level of difficulty. This book also provides enough practice material for the new syllabus changes of O-Level Mathematics (4024 & 4029) for the year 2018 and onwards. Relevant prerequisites are given at the beginning of each chapter so that students can build upon their prior knowledge before going to start with the exercises in the chapter. There is plenty of progressive and repetitive practice material that allows students to practice methods applicable to the topics. It also helps students identify their areas of weakness and misconceptions. This book will also provide sample past examination questions of early 80’s and 90’s, for not only O-Level mathematics but also for other examination boards like Edexcel, so that students will have a clear idea of examination patterns.
