This book has been written to meet the requirements of students who are reading the IGCSE 0417 syllabus. Ever since this syllabus was introduced, there has been a demand for a guide with questions and answers.

A dedicated attempt has been made to make the book useful and stimulating. Students often lack confidence when answering certain questions due to a lack of practice. In response, this book equips both students and teachers with a basic approach to answering questions.
