The Knowledge Quiz series is a deviously simple and effective way for students to revise for GCSE subjects. Put together by subject experts, these easy-to-use books feature tear-out quizzes to help students memorise the large body of knowledge that forms the basis of success in exams. Rather than just flicking through revision cards expecting things to stick in your memory, self-quizzing allows students to complete multiple copies of the same quiz and keep doing them until you get them right every time. Each book starts off with easy questions to get you going, followed by more difficult questions to really test you and embed the key knowledge. At the end of each section you'll find full answers. This edition will help students to effectively drill the essential facts necessary for success in the GCSE Biology exams.
