By working though the worked examples and advice from examiners, students learn how to avoid the common pitfalls and gain maximum marks in the exam. They include plenty of questions for students to practise and, for users of our main teaching resources, there is a link back to the Students' Books for further study. The Examiners' tips then reveal how students can maximize their marks. These books are designed for use throughout the year, whilst the topic is being studied. As books are topic based, they also can easily be used by schools that have bought other publishers' courses.
