This CGP Revision Guide is the perfect companion for students taking Edexcel's Grade 9-1 International GCSE Biology course (and it's great for the Biology parts of International GCSE Double Award Science too). Every topic has crystal-clear study notes and is packed with examples. We've included all the experiments students will need to know, a whole section on experimental skills and plenty of practice questions throughout the book (with answers at the back). To top it off, there's a free Online Edition of the whole book - just use the unique access code printed inside the cover to access it on a PC, Mac or tablet. A matching Biology Exam Practice Workbook (9781782946755) is also available.
