Diagnostic · 25 questions · 30 minutes

Thirty minutes, and you stop guessing what to revise.

Twenty-five questions, one each from twenty-five different topics, spread across all six Parts in proportion to their size. It marks itself, and what comes out is not a score — it is a map: which topics are solid, which are not, and which three to open first.

Retake it and it samples the topics it has not asked you about yet, so the map fills in rather than repeating itself.

One clock

Thirty minutes for twenty-five questions — about seventy seconds each. You can pause it once, and skipping is allowed.

No marking to do

Every question is multiple choice with a worked reason, so the map is ready the moment you finish.

It stays yours

The map lives in your own browser. No sign-in, nothing uploaded, and it is there when you come back.

Nothing is marked until you finish, and an unanswered question counts as unknown, not wrong — that keeps the map honest.

Want this map read by a human?

A map tells you which topics failed. It does not tell you why — whether it was the set-up, the sign, or a formula used outside its range. That is a conversation, and the first one is free.
