Designed to follow the latest CIE IGCSE syllabus, 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. We provide everything needed to ensure exam success including questions and answers, revision and assessment advice. Laid out in short chapters that correspond to syllabus sections, the book is easy to navigate and content is never overwhelming. Each chapter contains some information followed by a number of examples showing how that idea is used. Worked past paper questions demonstrate how real-life examination problems should be approached, and a large bank of graduated examination-style questions are included that will challenge students at every level.
