Written to support and enhance assessment alongside the pupil texts, these resources offer a range of material for the OCR specification. They provide test questions for each chapter together with detailed mark schemes to make assessment easy. Two versions of each question are provided, one allows pupils to write their answers in the spaces provided and the other requires pupils to have separate writing paper. Questions can be grouped according to needs. Master grids are provided to cut and paste tests together in a consistent format to use the resource in any order. Chapter tests can be grouped to form a module test after chapters. End-of-chapter examinations can also be produced in this way. A free non-calculator supplement organised by unit/chapter is also included in this resource.
