Part of the ST(P) graded series in mathematics, this book is intended for use in the third year of secondary schools, to enable pupils to achieve about Level 6 of the National Curriculum in mathematics for Key Stage 3. Some of the work covered goes beyond Level 6, in preparation for Key Stage 4 at the age of 16+. The exercises are divided into three types of question. The first kind is aimed at helping pupils to understand the work, the second is for quicker workers, for extra practice or for later revision and the third is slightly more difficult, for those who have managed the first type fairly easily.
