How it works

From one exam to clear progress

More than sitting a paper — a path with evidence behind every step.

  1. 01

    Mock

    Take a realistic full mock

    Pick your exam and subject, then sit the whole paper on the clock

  2. 02

    Evidence

    We read the evidence

    Every answer, time per question, flags and revisits

  3. 03

    Decision

    Know what to fix first

    And what is not worth your time yet

  4. 04

    Repair

    Fix it your way

    With a teacher, a book or the course you already have

  5. 05

    Recheck

    Measure again

    Confirm the weak spot is really gone

We measure and point the way — you never have to study with us.
