The most comprehensive coverage of the 2014 syllabus for both SL and HL, this completely revised edition gives you unrivalled support for the concept-based approach to learning, the Nature of Science. The only DP Biology resource that includes support straight from the IB, integrated exam work helps you maximize achievement. We were planning on ordering another publisher's resources but many of our IB teachers attended workshops and came back asking for Oxford. The quality of the text and online support package is the reason.
