How it works
- Questions adapt to you: get one right and the next tends to be harder; get one wrong and it eases off.
- One question at a time. You can't go back, so take your time on each one.
- No answers are shown during the test. You'll see a full review with explanations at the end.
- Optionally, say how sure you are on each question. It doesn't change your score.
- You can take it once every 7 days during the beta.
We store your answers, timings and any confidence ratings with your account, to check and improve the test. No age or other personal details.
