Our Higher Level GCSE Maths Revision Guide for the AQA course is packed with concise, student-friendly explanations of every topic, backed up with plenty of step-by-step examples, in CGP’s clear informal and (dare we say) humorous style. We’ve also included helpful grade stamps to show the difficulty level of each topic, alongside plenty of exam-style questions with answers at the back! QR codes throughout give quick and easy access to worked video solutions from our in-house experts, plus a selection of challenging online quizzes! A unique code in the front of the book gives you access to the free Online Edition of the whole book on your PC, Mac or tablet. From here, you can also view/print full step-by-step answers to all the exam-style questions!
