Book Description

From the same author as the popular first edition, the second edition of this trusted, accessible textbook is now accessible online, anytime, anywhere on Kerboodle. It breaks down content into manageable chunks to help students with the transition from GCSE to A Level study, and has been fully revised and updated for the new A Level specifications for first teaching September 2015. This online textbook provides plenty of examples and practice questions for
consolidation of learning, with 'Biology at Work', 'Key Skills in Biology' and 'Study Skills' sections giving many applications of biology throughout. Suitable for AQA, OCR, WJEC and Edexcel.
