This text offers a series of progressive questions which comprehensively cover the material for the AS and A2 examinations. The book can be used alongside any core text or series and with any A Level biology syllabus. The questions have been grouped into familiar topics and summary sections of key facts and concepts to be covered are included at the start of each chapter. These are followed by a variety of progressive questions designed to lead the students from the most basic application of each new idea through to a full understanding of the concepts involved. Synoptic style questions have been included so that practice in this difficult area can be gained before the terminal exam. Different sections show which questions are aimed at AS level and which at A2, and what you should know boxes at the start of each new topic indicate what students should have covered before starting the section.
