A structured skill-building workbook for differentiation in CAIE 9709 Mathematics Pure 1: each section opens with a fully worked example, then builds through graded practice questions to exam standard, 70 marks in total. Every question has a complete worked solution. Designed for students meeting the topic for the first time or rebuilding shaky foundations, and equally useful as a cover lesson that runs itself. Written by a serving A Level maths teacher and updated for 2026.
