Your estimated IQ with its range, your percentile and all six domain scores are shown in full. There is no paid tier and no certificate to buy.
A 12-question short form for a quick estimate, or the 60-question full form for a more precise one. Neither is timed.
No account and no email address. You can save the result to a free account afterwards, but you never have to.
The short form has 12 questions, two from each reasoning domain. The full form has 60, ten per domain, and narrows the range around your result.
There is no clock. Work in a quiet place, alone, without a calculator or search engine — the result is only as good as the conditions.
When you submit, you get an estimated IQ with its range, your percentile, and a separate score for each of the six domains. Nothing is held back.
| Short form | Full form | |
|---|---|---|
| Questions | 12 (2 per domain) | 60 (10 per domain) |
| Typical time | About 5 minutes | About 30 minutes |
| Range around your result | ±12 percentile points | ±7 percentile points |
| Best for | A quick first estimate | A more reliable profile |
The questions are organized around the Cattell–Horn–Carroll (CHC) model, the framework behind most modern intelligence batteries. Each domain is scored separately, because most people are noticeably stronger in some than in others, and that shape tells you more than a single number.
Working out the rule behind an unfamiliar pattern. It depends least on what you already know, and it carries the most weight in your overall result.
Relationships between words and ideas — analogies, meanings, the logic of a sentence. It draws on vocabulary and reading history, so it tends to grow with education.
Number series and quantitative logic. It tests reasoning about quantities, not arithmetic speed, and no question needs a calculator.
Turning shapes in your head and inferring how parts fit together. People who read maps and diagrams easily often score well here.
Holding several pieces of information in mind while you work with them. It is the domain most affected by tiredness, stress and interruptions.
Simple tasks that clinical tests time. Here there is no clock, so these items are scored for accuracy only and do not measure speed itself; the domain carries the least weight in your overall result.
Expect pattern-completion puzzles, word analogies, number series, mental-rotation items and short memory tasks. Every question has one correct answer, and the difficulty varies: the short form pairs an easier and a harder item in each domain.
If you would like to see worked examples first, our guide to IQ test questions explains each format with a sample item and its solution.
See sample IQ test questionsEach domain is scored on its own, then combined into one overall result. The domains are not weighted equally: each counts in proportion to how strongly that kind of reasoning relates to general ability, so fluid and verbal reasoning count most and processing speed least. Your overall position is the weighted average of your six domain percentiles, which pulls results slightly toward the middle. On the short form, with two questions per domain, differences between domains are mostly noise.
You see that overall position as a percentile and as an estimated IQ: the same position converted to the familiar mean-100 scale. It is an estimate, not a clinical IQ. Clinical tests are normed on large, representative samples; ours compares you only with its own test-takers — still fewer than 100 sittings per form (76 full and 49 short as of October 2026) — so results will shift as more people take the test.
Every result comes with a range — ±12 percentile points on the short form, ±7 on the full form, before conversion. Those widths are deliberately conservative, not a precise measurement of error. Read the range, not the single number: if two results' ranges overlap, treat the difference between them as uncertain.
We would rather you trust the result than be flattered by it, so here is the boundary stated plainly.
On standard IQ tests, 100 is the average by design and the standard deviation is 15. About 68% of people score between 85 and 115, about 95% between 70 and 130, and roughly 1 person in 44 scores 130 or higher. Those proportions come from the bell curve itself, not from any one study.
On this test, an estimated 100 is the middle of our own sample: half of test-takers placed above it and half below. A mid-range result is the ordinary outcome, not a disappointing one.
