The "Target Science" books are aimed at the average/below average student studying for public examinations at age 16 or above. The texts are organized in double-page-spreads and designed to be as accessible as possible. There is a much higher proportion of "open space" used to help lower ability students. The reading level has been closely controlled and the amount of text restricted. Glossaries of new terms are provided at the end of each chapter. Examination-style questions are included.
