FAQ
Frequently asked questions
Everything you might want to know before (or after) you take the test.
Is this IQ test really free?+
Yes — completely. You get your full estimated IQ score and a per-category breakdown the instant you finish. There is no sign-up, no email wall, and no payment at any point. Many 'free' IQ sites make you take a long test and then charge $20 to see your result; we never do that.
Do I need to create an account or give my email?+
No. You can take the test and see every part of your result without an account, an email address, or a credit card. The test is scored in your browser and your answers never leave your device.
How is the IQ score calculated?+
Each of the 30 questions has a difficulty weight. Your weighted performance is mapped onto the standard IQ scale, which has a mean of 100 and a standard deviation of 15 (a 'deviation IQ'). That means about 68% of people score between 85 and 115. We explain the full method on our methodology page.
How accurate is an online IQ test?+
An online screening test like this gives a reasonable estimate, but it is not a substitute for a clinically administered, individually-normed test (such as the WAIS) given by a psychologist. Treat your score as a fun, useful snapshot with a meaningful margin of error — not a diagnosis.
What kinds of questions are on the test?+
Five types: abstract/matrix reasoning (Raven's-style visual patterns), number series, verbal analogies, logical deduction, and spatial reasoning. The visual sections are 'culture-fair', meaning they don't depend on language or schooling, so the test works well across backgrounds.
How long does the test take?+
About 20–30 minutes. There's a soft 30-minute timer because timed performance is part of what IQ tests measure, but you can move at your own pace and revisit questions before submitting.
What is a good IQ score?+
Scores from 90 to 110 are considered average — that's where most people fall. 110–119 is high average, 120–129 is superior, and 130+ is the top ~2% used as the threshold by societies like Mensa. Remember that the majority of people score in the average band, and that's completely normal.
Can I retake the test?+
Absolutely, as many times as you like. Keep in mind that once you've seen the questions your score may rise a little on repeat attempts (a practice effect), so your first attempt is usually the most representative.
