If you want to improve your mathematical skills in GCSE or IGCSE Chemistry this book will provide superb additional support to help you achieve this. It covers all of the calculations you will encounter using plenty of explanations, examples and practice questions with answers. Calculations are introduced and broken down into simple steps that can be applied to each problem regardless of difficulty. The questions start at a foundation level and become increasingly harder as the topic exercises progress. This allows students of all abilities to gain good experience in solving these problems and to make progress as a result. The more challenging questions at the end of each topic will also help students who are preparing for A level Chemistry. These methods have proved useful in the past and have allowed students to realise that becoming competent in chemical calculations is absolutely possible with a bit of practice and guidance.
