Part of the ST(P) graded series in mathematics, this book completes coverage of Levels 8 and 9 of the National Curriculum and contains exercises divided into three types. The first type is aimed at consolidation, the second is for extra practice or later revision, and the final type is of more demanding questions. Multiple-choice questions are included as a self-test to confirm understanding and as a basis for class discussions, and the book ends with some general revision exercises of examination-type questions.
