I've been using Exam Ninja books for around five years to help my nine-year-old daughter with her schooling. We buy a set for each year and my daughter works her way through them, a little each day, with my assistance. These are an excellent resource for boosting a child's learning journey and supporting the school curriculum.

About the GCSE Maths OCR Knowledge Retriever - Foundation

If your Year 10 or Year 11 child is studying Foundation Maths for OCR GCSE, the GCSE Maths OCR Knowledge Retriever - Foundation is designed to turn their revision into active recall practice. Paired with the separate Knowledge Organiser, this retrieval workbook helps pupils test themselves on algebra, geometry, statistics, ratio and proportion—all the essential Foundation topics—so they're confident they've truly learnt the material rather than simply reading it.

Each page mirrors a topic from the Knowledge Organiser, leaving blanks for your child to fill in key facts, formulae and methods from memory. After the first pass, a tougher second test challenges them to retrieve the same information without prompts, embedding it more deeply. Mixed practice quizzes at the end of each section combine topics, mimicking exam-style questions and helping pupils spot connections across algebra, geometry and statistics. Answers are printed at the back, so your child can check their work independently and identify any gaps without waiting for someone else to mark it.

The result is calmer, more effective revision: pupils discover exactly which concepts they've mastered and which need another look, building genuine understanding instead of false confidence. Because the book follows the OCR Foundation specification closely, every topic aligns with what examiners expect, giving you peace of mind that your child is preparing for the right content. CGP publishes the workbook as a physical book, dispatched quickly so revision can start straightaway.

This retrieval workbook suits Foundation-tier students in Years 10 and 11 who already have access to the matching Knowledge Organiser and want a structured, no-fuss way to test themselves. It works best when used little and often—short, focused sessions that turn passive reading into active learning and help build the recall speed and accuracy needed on exam day.

  • Covers OCR Foundation GCSE Maths topics including algebra, geometry, statistics, ratio and proportion
  • First retrieval test after initial learning, then a harder second test to deepen recall
  • Mixed practice quizzes combine topics and mirror exam-style challenge
  • Answers included at the back for independent checking
  • Designed for Year 10–11 pupils (ages 14–16) studying Foundation tier
