The material is tailored to the new specification so you have everything you need in just one book. This work features: straightforward structure based around units of work - so it is easy to find the relevant content; plenty of worked examples showing the key techniques and thousands of questions to check students understanding; and hundreds of past paper questions that students can use for practice. The revision programme includes: in-built revision from the beginning of the course so that it is part of a regular process and not left to the last minute; prior learning points and 'test yourself' pages for each unit so students can check their progress; regular skills breaks allowing students to use their skills in unfamiliar contexts, ensuring they can transfer the skills learnt; and In Focus pages providing revision at the end of the course.
