These resources have been created for the Cambridge IGCSE (R) and O Level Additional Mathematics syllabuses (0606/4037), for first examination from 2020. The Cambridge IGCSE (R) and O Level Additional Mathematics Practice Book works alongside the coursebook to provide students with extra materials so they can practise the required syllabus skills. The exercises have further worked examples to help students approach the questions within. Answers are provided in the back of the book.
