How the test works
Tasks go from easy to hard. The first ones take seconds; the last ones need real thought. Task types are mixed to test different sides of thinking:
- Matrices. A 3×3 grid of figures with one cell missing. Find the pattern across rows and columns: the shape, number, fill, size or rotation changes.
- Number series. Find the rule behind the series and continue it.
- Words. Analogies (“bird is to nest as bee is to…”) and finding the odd one out.
- Logic. Short reasoning puzzles where the first obvious answer is often wrong.
How IQ is calculated
IQ is not the number of correct answers but a comparison with other people. The scale is built so that the average is 100 and the standard deviation is 15. About two thirds of people score between 85 and 115, and about 2% score above 130.
| IQ | Level | Share of people |
|---|---|---|
| 130 and above | Very high | about 2% |
| 115–129 | Above average | about 14% |
| 85–114 | Average | about 68% |
| 70–84 | Below average | about 14% |
| below 70 | Low | about 2% |
All tasks were created for this test following the principles of classic intelligence tests. The conversion from score to IQ is preliminary for now: we refine it using anonymous results that cannot be linked to anyone.
How to get a fair result
- Set aside 25 minutes when nobody will distract you.
- Do not use a calculator, search or hints: the test measures your own speed of thinking.
- Stuck? Skip the task and come back to it at the end.
- If you do not know the answer, guess rather than leave it blank: a skipped task counts as wrong.
