Provide the support for successful and in-depth study, with chapters presented in syllabus order, past IB exam paper questions and links to Theory of Knowledge.

Material for Higher Level and Standard Level is clearly identified and key terms are simply defined, with examples drawn from a wide range of international sources.

Chapters open with a list of 'Starting points' that summarise essential concepts. Photographs, electron micrographs and full-colour illustrations complement the text, and illustrate principles and processes in context. Topics and Options coverage accurately reflect the Objectives and Command terms in which syllabus assessment statements are phrased.
