Biology by Example is a revision guide aimed at the AQA GCSE science courses grades 9-1. It does have extra content, so it also covers the majority of the Edexcel and other UK exam boards as well. Biology by Example like the other guides in this series, (Physics by Example and Chemistry by Example) are different to other revision guides on the market because they are centred around practice questions with fully worked and solved solutions. This means the student/teacher can follow the method step by step of how to approach and solve exam style questions in the three sciences. Including hints, tips and common mistakes students make to help describe the approach because it is necessary to fully understand successfully answer exam style questions in GCSE science. The guides all contain self-testing sections with answers and space for working.Biology by Example contains a huge array of different styles of questions from long answer, comprehension, multiple choice, matching sentence starters and endings, graph analysis and straightforward recall to name but a few. The three guides together have around 800 practice questions with solutions fully worked and written in an easy-to-follow way. This gives the student or teacher probably the most comphrensive source of revision material or lesson planning material for school science there is currently on the market.
