One of the hardest things about revision is planning what to revise and when. "Active Revision" helps students to structure their revision effectively. Key skills are revised step-by-step in the full colour book, whilst interactive tests on the CD-ROM check students' understanding. An electronic revision planner and timetable helps students to plan their revision effectively. "Active Revision" should provide students with an insight into where to concentrate their revision time and energies. An exam practice section at the end of the book provides an opportunity for students to put all the skills into practice and shows them how to improve their grades.
