This book was written to aid students in their revision for the Cambridge IGCSE Computer Science examination. The first chapter of this book serves as a quick introduction to the tools you will need as well as some basic information to get started. The next three chapters contain practice questions to prepare for the examination. Answers can be found at the back of the book for marking and correction after the practice questions have been attempted.The questions and answers were selected to be representative of what students should expect to encounter in the actual examination. It is our hope that using this book as a revision aid would adequately prepare students for the nature and difficulty of the questions they will likely encounter, and the appropriate way to answer them.Click  to view a brief flip-through of the book.
