How practising here works

  1. 01

    Answer for real

    An exam-style question, in the exact format of the paper. You write or think the full answer first, no multiple choice.

  2. 02

    Mark like the examiner

    Reveal the real mark scheme and tick the points you actually made. You learn precisely what a full-mark answer contains.

  3. 03

    Watch mastery climb

    Every mark you award feeds your mastery, per topic. You always know what to revise next and what already sticks.
