Fully endorsed by Cambridge, this revision guide will provide revision material which is presented in a clear, concise, but not too condensed format, appropriate for international students aged 14-16. They may be used for study and homework throughout the year but are predominantly intended as a student revision purchase. Suitable for all students, it will stretch those of a lower ability while challenging and providing a wealth of exam practice for students of higher ability. “Big ideas” will help to guide revision and show students what learning outcomes they should be aiming for. Visual and EAL learners will be supported by the diagrams and figures that are used to illustrate all concepts, ranging from the elementary to the complex. Core and Extended material is distinguished and questions are separated into different levels. We provide everything needed to ensure exam success including questions and answers, revision and assessment advice.
