Built on ICAR · 33 questions · about 9 minutes · no time limit · instant score · no email
How well you reason through problems you have not seen before. This IQ test has 33 questions: 20 matrix puzzles, 6 series and logic problems, 4 verbal and 3 numerical. It does not measure knowledge, creativity or personality. How you act and work with people is what a free DISC personality test shows.
Your correct answers are placed on a scale with a mean of 100 and a standard deviation of 15. About two people in three score between 85 and 115, and about 2% score 130 or more. On this test each correct answer is worth 3 points, and 16 right out of 33 lands at 100.
About 9 minutes. That is the median for first attempts on this test, and there is no time limit. A psychologist’s full assessment, such as the WAIS-IV, usually takes an hour or more.
Accurate enough to place you, not to diagnose you. Scores move on a retake: of 735,563 people who took this test twice, 48.3% changed by ten points or more. Unsupervised online scores also run higher than supervised ones, so read yours as a range of several points.
100, by definition, at every age. Each age group is scored against its own middle, which is set at 100. The average range runs from 90 to 109 and holds half of all scores.
Your IQ score, how you did on each kind of question, and an explanation for every question you missed.
All of that is free. A certificate is optional and sold separately.
Sample report
After you finish, you can go through every question you missed, with the right answer and why it is right.
A real report for raw scores of 14, 3, 4, 2. The marked stretch on each bar is the typical range for that section, and each small square is one question. Yours is drawn the same way from your own answers.
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.
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.
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.
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.
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.
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.
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.
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.
A grid of shapes with one cell missing. You find the rule that runs across the rows and down the columns.
Number and letter sequences, a counting puzzle, and a rate problem built to punish the first obvious answer.
An opposite, a synonym, an analogy, and the word that does not belong with the others.
Everyday data questions: a percentage change, an average and a median, taken from small tables.
Try one
What comes next in the sequence? 3, 7, 13, 21, 31, …
43. The gaps between the numbers grow by two each time (4, 6, 8, 10), so the next gap is 12, and 31 + 12 = 43.
A practice question, not one from the test. More practice questions with answers
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.
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.
Drag to see how each answer moves the score.
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.
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.
The top of the scale, and the range that high-IQ societies such as Mensa look for on a supervised test.
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.
Above the middle of the scale, and a strong result on these puzzles.
The middle of the scale, where half of all scores on it fall. For everyday life, this range is simply normal.
A little below the middle. On an online test, rushing or reading in a second language can pull a score into this range.
Well below the middle. One short online test says little here, and a calm retake on another day often reads differently.
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.
Labels are the Wechsler Adult Intelligence Scale (WAIS-IV) bands on a scale with a mean of 100 and a standard deviation of 15. Every percentile from 55 to 160 is on the IQ scale chart. What a specific score means
Average
A wide street, not a point
Half of everyone scores between 90 and 109. Inside that range, a difference of five points says more about the day than about the person.
Online
Scores run high
People who look for an IQ test online score above the general population, and an unsupervised test is easier to do well on. Treat your number as a position on this test.
Percentiles
Often the more useful number
A percentile says what share of people you outscored. 115 and 120 sound close, but one is the 84th percentile and the other the 91st.
Straight answers on taking the test, reading your score and what to trust.
Taking the test
Take a structured reasoning test and see where your score falls against other people’s. That is all an IQ level is: a position on a scale where 100 is average. This test takes about 9 minutes and shows your score and percentile as soon as you finish. Only an assessment by a psychologist gives a clinical IQ.
Take it once, somewhere quiet, when you are rested and in no hurry. There is no time limit, and 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. It works on a phone or a computer, so choose whichever helps you concentrate. To warm up, try a few practice IQ questions first.
Largely yes, because very little of it depends on English. Of the 33 questions, 20 are shape puzzles with no reading, and only 4 are verbal, which is 12 points at most. The test also runs in 12 languages, with verbal questions written for each one, so choose the language you think in.
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.
Your 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. On clinical tests these numbers mean the same at any age, because average IQ by age is set at 100 for every age group.
Because online scores tend to run higher than supervised ones. People who look for an IQ test score above the general population, you sit it alone and in your own time, and the reference point here is fixed rather than re-estimated from takers. So read your number as a position on this test. Our guide to how accurate online IQ tests are explains the gap.
Yes, as often as you like, but expect the number to move. Of 735,563 people who took it twice, 48.3% changed by ten points or more, and very high first scores usually came down. A calm first attempt is the fairer read, and what your IQ score means shows how far each score tends to move.
IQ explained
IQ stands for intelligence quotient. A quotient is the answer to a division, and the first IQ was exactly that: mental age divided by real age, times 100. A ten-year-old reasoning like a twelve-year-old scored 120. Modern tests dropped the division and place you on a scale where 100 is the middle, as how IQ tests work explains.
Around 140 by custom, though no test defines genius. The number comes from Lewis Terman’s 1916 table, which labelled 140 and above “near genius or genius”. Today about one person in 250 scores that high. Above 145, tests run short of hard questions, so the numbers get less exact just as the claims get bolder. The IQ score chart shows every level.
Nobody knows Einstein’s IQ, because he never took a modern IQ test. The 160 you see quoted is an estimate made from his work, and the same goes for Stephen Hawking. The most famous record is Marilyn vos Savant’s 228, listed by Guinness in the 1980s before it retired the category. Claims of 200 or more come from old formulas or extrapolation, because most modern tests stop at about 160.
Yes, a little, and mostly slowly. Adult scores are largely stable, though a 2018 meta-analysis suggests each extra year of formal education adds roughly 1 to 5 points. The 3 to 5 points people often gain on a second sitting come from knowing the questions, not from a sharper mind. Here is what the evidence says on whether you can improve your IQ.
Trust and cost
It is a real reasoning test, built on ICAR, an open question bank published by psychologists, and scored the same way for everyone. In published validation, ICAR scores tracked an established intelligence test closely (r = .81). This is still a short online test, not a psychologist’s battery such as the WAIS-IV, so it can place you but not diagnose you. Scores can move ten points between sittings, so read yours as a range. Our test methodology has the detail.
In person, with a psychologist, because no online test gives an official IQ. Clinical tests such as the Wechsler scales and the Stanford-Binet are given one to one. Mensa admits people through its own supervised test or approved earlier results, and says its online challenge will not qualify you. Both cost money, so a free test is a sensible first read. The Mensa IQ test guide covers the route in.
It is free, and there are no hidden charges. 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, which are a one-off purchase. Nothing in your result is held back to sell them, and our refund policy gives you 60 days if you buy one and change your mind.
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. The two sites simply have similar names.
It is safe: you need no name or email to take the test, and 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. The detail is in our privacy policy.
