Compiled by Anne-Michelle d’Anjou and Richard O’Shea © Mickledore Publishing 2011 The aim of this CD-ROM is to provide a convenient and comprehensive set of short mathematical questions covering all the relevant topics listed in the new specification for GCSE Astronomy provided by Edexcel for first examination in June 2011. Each mathematical topic is contained within a separate ‘chapter’ file (presented in both Microsoft ® Word (for PC) and PDF formats). Each chapter contains a short tutorial followed by worked examples and practice questions for you to answer. Each file can be accessed by simply ‘Exploring’ the CD using ‘My Computer’ and double clicking on the relevant topic to open it. All solutions are contained in a separate file. The questions vary in style and level of difficulty in order to reflect the range of questions found in recent examination papers and Edexcel support material. Hints and advice on solutions are provided, along with background information (tutorials) on all topics. Some questions require the use of a mathematical formula, whereas others can be solved by applying thought and reasoning. Where possible, real data has been used, and it is hoped that the diversity of questions will provide opportunities for students to not only consolidate their knowledge and understanding of the subject matter but also to develop the key mathematical skills that are relevant to the study of Astronomy and other Science-based subjects at GCSE level.
