This revision guide is a partner to the matching text book (which is IGCSE Biology Student Book) and, together with the student CD, it makes a valuable aid to study. It's bright, colourful, lightweight (a paperback just a bit smaller than A4 and very easy to read because the text is broken up into bite-sized chunks and liberally illustrated with large, colour diagrams. It's organised, as you would expect, into logical chapters in sections A to F. The matching text book contains a great deal of detail and background reading, all of which is essential for the student, and this revision guide starts each chapter with bullet-point facts, followed by illustrated salient details, clearly set out, for a couple of pages. For example, the chapter (21) on "using microorganisms", describes fermentation and biotechnology and modern biotechnology, together with handy "Examiner's Tips" which are boxed and coloured, in the margins. There's a diagram in colour of industrial fermentation and a flow-chart showing the process for making beer and yoghurt. On the third page is a paragraph explaining how the student can demonstrate experimentally how respiration takes place. This is followed by the Questions section, which is very useful for checking knowledge and understanding - the student may have to refer to the main text book for some of the answers. This revision guide should be used in conjunction with the CD and main text book, and I would urge a student to remember to refer to the glossary at the end, as well as the index. This helpful book it ends with three pages of notes on "preparing for exams", including tips on exam language and how to respond to questions which ask "name; complete; describe; give; explain; discuss", with worked examples. Well done to author Ann Fullick for making biology accessible and interesting.
