This book has been specially written to help you revise for Maths Higher specification A by Edexcel. Although the book starts gently with some basic reminders its main aim is to work towards getting a grade B, A or A* in the exam. Hopefully, some of the material will already be familiar to you. If you work through most of the examples in this book as well as the practice questions you are very likely to pass with a very good grade. This second edition has many worked examples and practice questions to help you become familiar with what to expect in the exam.
