There are two Student Books, one for International AS level and one for International A Level, and they provide: * A chart at the beginning of each book shows where each specification point is covered. * Learning objectives set expectations at the beginning of each chapter, and Getting started activities engage students' interest. * A clear layout, with regular illustrations, diagrams, and tables to explain new concepts. * Definitions of key terms throughout and a glossary at the back of each book. * Varied activities embed understanding, and frequent exam tips link new learning to the final examinations. * Thinking Like a Psychologist sections encourage deeper thought and application of learning in other contexts. * Checkpoint questions and exam practice questions facilitate revision at the end of each chapter.
