This work fully prepares students of all abilities for GCSE/Standard Grade examinations. It motivates students using a unique three-way differentiation scheme. Parallel foundation and higher students' books include activities pitched at two levels with corresponding worksheets graded into lower and higher ability levels. Extra practice and teacher support is provided through two levels of worksheets which are suitable for photocopying, thereby providing scope for grammar practice, revision, single skill and mixed skill work. A carefully planned assessment programme fulfills GCSE/Standard Grade requirements. Teacher's resource files contain material designed for photocopying.
