This book is written by a Principal Moderator and a Senior Team Leader for the AQA. The new edition includes more gradual progression from Foundation to Intermediate, with a lower language level than the previous edition. It is organised by the AQA B modules, with sample exam papers and coursework advice, where appropriate, at the end of each module. Margin notes provide extra clarification to aid comprehension. Beginning and end-of-chapter summaries lead to a better understanding of each topic.
