Extended Mathematics for Cambridge IGCSE provides for the second year of a two-year course leading to the Cambridge IGCSE Mathematics Extended Level examination from Cambridge. Students may either study the whole of the Core course in their first year, followed by the Extended in their second year, or they may study Chapter 1 from Core followed immediately by Chapter 1 from Extended. Either way, the books are designed to be worked through sequentially and can be used both as classroom textbooks and for self-study.
