Practise any GCSE or iGCSE topic with questions generated fresh each time, so you can't run out or learn the answers by heart. Covers all six strands — Number, Algebra, Ratio and Proportion, Geometry, Probability, and Data and Statistics — at both Foundation and Higher tier. Your answer is marked instantly and your accuracy on each topic feeds straight into your skill tree. 165 interactive courses. Every topic on the GCSE and A-Level specifications has its own course. Each teaches the method through worked examples, then asks you to try questions yourself with instant feedback — so you find out whether you've understood as you go, rather than at the end of a page. Over 20 revision engines with unlimited questions. The engines generate a new question every time rather than serving from a fixed bank, so you can't run out of practice or memorise the answers. They mark your work instantly and accept any mathematically equivalent form, whether you write an answer as a surd, a fraction or a negative index. Over 100 worksheets with full solutions. Printable PDF worksheets for every topic, with questions grouped into fluency, reasoning and problem solving, and step-by-step worked solutions in a separate file. A skill tree that tracks everything. Your accuracy on each topic is recorded as you work, so you can see at a glance what's secure, what's developing and what hasn't been started. Diagnostic reports turn that into a specific list of what to revise next. Free student tools. A formula sheet builder that creates a personalised sheet of everything you need to memorise, an exam paper builder that assembles a custom paper from any combination of topics, and a revision timetable maker.

The same approach for A-Level and International A-Level. Choose a single topic or a whole exam module — Pure 1 to 4 — and work through generated questions with instant marking. Any mathematically equivalent answer is accepted, so writing a result as a surd, a fraction or a negative index all count as correct.
