What is an IQ test?

A set of reasoning problems whose score is placed on a scale where 100 is average. This one has 33 puzzles across four kinds of reasoning, takes most people about 9 minutes, and shows your score the moment you finish.

What you get

An IQ score, your percentile, and a breakdown across matrix, series, verbal and numerical questions. It opens on the results page with no email and nothing to unlock.

What it is good for

Satisfying real curiosity, seeing how your reasoning compares, and a first read before a supervised test such as Mensa's. It also makes a fair warm-up for aptitude tests at work.

What it will not do

Diagnose anything or replace a psychologist's assessment. It cannot see creativity, judgement or persistence. Online scores also run higher than supervised ones, so read yours as a position on this test.

How to check your IQ

Your IQ is a position on a scale where 100 is the middle. To find it, you take a reasoning test scored against that scale, whether you call it an IQ test, an intelligence test or an IQ quiz. Five steps get you the truest reading from this one.

  1. Find a quiet ten minutes

    Most people finish in about nine minutes, and there is no time limit. Silence notifications and close other tabs before you start.

  2. Take your time

    Rushing costs more than people expect. In our US data, people who finished in under two minutes averaged about 30 points lower than people who took ten to fifteen.

  3. Read each grid as a rule

    Twenty of the 33 questions are matrix puzzles. Look for what changes along each row, then check that the same rule holds down each column.

  4. Take it in your own language

    The test runs in 12 languages, and the verbal questions depend on reading them well. If English is not your first language, choose yours from the language menu at the foot of the page.

  5. Count your first attempt

    A second attempt usually scores a little higher, because the questions are familiar by then. Your first calm attempt is the fairest read.

Only an assessment by a psychologist gives a clinical IQ. An online test gives you a well-founded estimate.

What the 33 IQ test questions measure

Four kinds of reasoning, each question multiple choice with four options. None of it needs specialist knowledge.

There is no time limit. Taking your time helps more than most people expect.

Original research

What 152,543 answers revealed about IQ scores

After the last puzzle, and before the score appears, we ask each person one question. Then we line the answers up against the scores. Six results stood out.

Confidence12,097 adults

Score compared with people of the same age and country

Each dot is about 5 adults. The bright line marks each group's average.

  1. 01Confidence

    Think your IQ is way above average? You might be wrong

    People sure they would ace it scored below average

    Points above or below the adult average

    We asked 30,075 people, before they saw their score: Before you see it: where do you think your score will land?

    Adults who expected to land well above average scored 4.3 points below the adult average. The people who guessed one step lower, above average, beat them by 8.4 points. Only 7% of adults made the boldest guess.

  2. 02Sleep

    Does sleeping too much lower your IQ?

    The longest sleepers scored 9 points lower

    Points above or below the adult average

    We asked 31,169 people, before they saw their score: How many hours did you sleep last night?

    Adults who slept nine hours or more the night before scored 8.7 points below the adult average. The top group was not the well rested: it was people on five to six hours, 10.6 points ahead of the long sleepers. One question cannot say why, so read it as a pattern, not as advice.

  3. 03AI use

    Is ChatGPT making you smarter or dumber?

    Daily users scored 5 points below occasional users

    Points above or below the adult average

    We asked 30,491 people, before they saw their score: How often do you use ChatGPT or another AI assistant?

    Adults who use an AI assistant a few times a week scored highest, 3.3 points above the adult average. Daily users landed 4.9 points behind them. The lowest group never uses AI at all, 3.9 points below average.

    Are Mac users smarter than PC users?

    A dead heat. But computer users beat phone users by 6 points

    Points above or below the adult average

    We recorded the device on 185,649 first attempts: iPhone, Android, Windows PC, Mac or iPad, Chromebook

    Adults on a Windows PC scored 6.1 points above adults on an Android phone, and 5.2 above iPhone users. Mac against PC? A dead heat, 0.1 points apart. iPhone did edge out Android, by 0.9 points.

  5. 05Star signs

    Do smart people know their star sign?

    People who know their sign scored 5 points higher

    Points above or below the adult average

    We asked 29,158 people, before they saw their score: What's your star sign?

    Adults who did not know their sign scored 5.4 points below those who named one. Which sign made no difference: all twelve landed within 2.8 points of each other, and none could be told apart from another.

  6. 06Cats or dogs

    Cat people or dog people: who is smarter?

    Too close to call. But people who love both beat people who like neither

    Points above or below the adult average

    We asked 31,650 people, before they saw their score: Cat person or dog person?

    Adults who said both scored 2.6 points above adults who said neither. The old argument stays unsettled: cat people and dog people were 0.6 points apart, too close to call.

Method

How we gathered this data

Every figure above comes from people who took the test on this page. Nothing is modelled, and nothing is borrowed from other sites.

Read the full methods and download the data
One question, before the score
Everyone takes the same 33 puzzles, with no time limit. After the last one, and before the score appears, each person sees one question. Nobody answers knowing their result.
Picked at random, free to skip
The question is picked at random from the four live that week, and it can be skipped. Each one runs for seven days and collects about 31,000 answers. These ran from 22 – 29 September 2026.
Compared like with like
Each group is compared with all adults who answered the same question, after adjusting for age and country. Under-18s and people who gave no age are left out of these figures.
Stated only when it holds
We report a difference only when it holds at 95% confidence, after correcting for every comparison on the page. Where groups cannot be told apart, we say so.
Gaps, never group IQs
Online scores run above 100, so we publish gaps in points and never an average IQ for a group. The device comes from the browser, not a question: 185,649 first attempts, 17 – 29 September 2026.
What it cannot show
These are people who chose to take an online test, not a random sample of any country. The figures show how answers and scores line up. They do not show that one causes the other.

Average IQ by country

Which countries have the highest IQ?

Here are the ten highest averages on our test. Then the part national IQ tables leave out: how little separates one country from the next.

The ten highest country averages

Score index for adults. The UK sample is 100, and one question is worth three points.

Score index, UK sample = 100

Each bar is the gap from the UK sample, and the thin line is the 95% range. The ten are 2.8 points apart from first to tenth, and the first seven cannot be told apart from one another. 58 of the 76 listed countries sit within one question of the UK.

Between countries, or between people?

96.9% of the variation in scores is between people in the same country

That is across 74 countries. Only 3.1% of the variation lies between one country and another.

Is this a real IQ test?

It is a real reasoning test, built on published research and scored the same way for everyone. It is not a clinical assessment, and it does not pretend to be one. Here is what that means for how accurate your score is.

How your IQ is calculated

Every question counts the same. Each right answer is worth three points, and 16 or 17 correct out of 33 lands at about 100. Nothing is weighted or curved, and your score is worked out the moment you finish.

IQ120 23 of 33 correct

Drag to see how each answer moves the score.

60 80 100 120 140 05101520253033 Questions correct

The scale stops at 55. Below that, a score reads 55.

Built on published research

The 33 questions are built on the International Cognitive Ability Resource (ICAR), an open bank of reasoning items that psychologists developed and published for research. Twenty of them are matrix puzzles, which depend on finding rules and holding them in mind. Researchers have also tested how these open measures behave in large online samples.

What it can and cannot tell you

It gives a fair estimate of how well you reason through these kinds of puzzles on the day. Reasoning scores predict later school results fairly well, but they cannot see creativity, judgement or persistence, and this test cannot diagnose anything. Average scores have also risen from one generation to the next, so read yours as a position on this test, not a fixed quantity.

Where to get an official score

No online test gives an official IQ, and unsupervised scores usually run higher than supervised ones. Psychologists give the Wechsler scales or the Stanford-Binet one to one. Mensa accepts its own supervised test or approved earlier results. How to qualify for Mensa

Free, with one optional purchase

Your score, your section breakdown and an explanation of every question you missed are free, with no email and no card. The only thing for sale is an optional certificate and report, paid once. It is not a subscription.

What your IQ score means

100 is the middle of the scale. Every 15 points is one standard step away from it, so two people in three score between 85 and 115.

  • 130 and above Very Superior

    The top of the scale, and the range that high-IQ societies such as Mensa look for on a supervised test.

  • 120 to 129 Superior

    Well above the middle of the scale. On a short test, a few questions either way can move a score in or out of this band.

  • 110 to 119 High Average

    Above the middle of the scale, and a strong result on these puzzles.

  • 90 to 109 Average

    The middle of the scale, where half of all scores on it fall. For everyday life, this range is simply normal.

  • 80 to 89 Low Average

    A little below the middle. On an online test, rushing or reading in a second language can pull a score into this range.

  • 70 to 79 Borderline

    Well below the middle. One short online test says little here, and a calm retake on another day often reads differently.

  • 69 and below Extremely Low

    The bottom of the scale. A result here on a short online test is not a diagnosis. If it worries you, a psychologist can give a full assessment.

Common questions about this IQ test

Is this IQ test really free?

Yes. Your score, percentile and section breakdown open on the results page without an email, an account or a card. We earn money from an optional certificate and report. You can ignore both, and nothing in your result is held back to sell them.

How long does the IQ test take?

About nine minutes for most people, and there is no time limit. Rushing costs more than people expect. In our US data, people who finished in under two minutes averaged about 30 points lower than people who took ten to fifteen.

What is a good IQ score?

Anything from 110 up is above average, and 120 puts you ahead of about nine people in ten. The usual Mensa line, 130, is reached by about one person in fifty. For everyday life, anything between 90 and 109 is simply normal. The IQ scale chart has every percentile.

Is MyIQTested the same as myIQ.com?

No. MyIQTested is an independent site with no connection to myIQ.com or Cerebrum IQ. Here your score, percentile and breakdown appear without an email or a card, and nothing is charged unless you choose to buy the optional certificate.

Is this IQ test for adults or children?

Both: half of the first-time takers who tell us their age are under 18. Read a child’s score with care, though. Everyone is scored against the same reference point, so a child’s number is not adjusted for age the way a clinical test is. For school gifted testing, our CogAT practice test is closer to what they will actually sit.

Can I retake the IQ test?

Yes, as often as you like, but expect the number to move. Of 894,632 people who took it twice, 35.1% changed by ten points or more, and very high first scores usually came down. A calm first attempt is the fairer read.

How is an IQ score calculated?

By counting correct answers and placing the count on a scale where 100 is the middle. Here every question is worth three points, and 16 or 17 right out of 33 lands at about 100. The reference point is fixed rather than re-estimated from takers, which is one reason online scores run high. The old formula, mental age divided by real age, only ever worked for children.

What happens to my answers?

Your score is worked out in your browser. Like most sites, we keep anonymous usage records, such as scores, timing and approximate country, and publish only aggregate figures, such as our research pages. You do not need a name or email to take the test. The detail is in the privacy policy.
