How this free IQ test works
- Start the test. You get 36 questions and a 25 minute countdown. There is no sign-up and no email required.
- Answer each question. Choose an answer, then move on. You cannot go back, so take a moment to read each question carefully.
- Watch the clock. If time runs out, the questions you have answered are scored and the rest count as incorrect. You can pause with the exit button and resume later.
- Get your result. You instantly see your estimated IQ score, your accuracy in each section, and a review of every question you missed with an explanation.
The questions, numbers and answer options are generated at random, so every attempt is different. Your result can be copied or saved as an image.
What the four sections measure
Pattern reasoning
Visual matrices test abstract and spatial reasoning. You look at a grid of shapes, work out the rule that connects the rows and columns, and pick the option that completes the pattern. This kind of question appears in many non-verbal reasoning tests.
Number reasoning
Number sequences test numerical reasoning. You find the rule behind a series of numbers, such as adding a fixed step, doubling, alternating operations or following square and prime numbers, and work out the missing term.
Logical reasoning
Logic questions test deductive reasoning and verbal reasoning. You draw conclusions from statements, rank people from clues, solve analogies, crack simple codes and follow letter and calendar patterns.
Applied reasoning
Applied questions test practical problem solving with everyday maths, such as percentages, speed, time, money and rates. They show how well you can turn a real-world situation into a calculation.
IQ score chart: what do the scores mean?
On standardised IQ tests, scores are scaled so that the average is 100 and the standard deviation is 15. About two-thirds of people score between 85 and 115, and roughly 95 in 100 score between 70 and 130. This test uses a simple, capped scale from 70 to 130, so use the table below to read your result.
| Correct answers | Estimated IQ | Description |
|---|---|---|
| 0 to 5 | 70 to 78 | Below average |
| 6 to 11 | 80 to 88 | Low average |
| 12 to 23 | 90 to 108 | Average |
| 24 to 29 | 110 to 118 | High average |
| 30 to 35 | 120 to 128 | Superior |
| 36 | 130 | Very superior (top of this scale) |
The scale stops at 130 because 36 questions cannot reliably measure beyond that. A perfect score shows you answered every question correctly, not that your IQ is exactly 130.
How is IQ calculated?
A professional IQ test, such as the Wechsler or Stanford-Binet scales, compares your performance with a large reference group of people of the same age. The result is converted into a score where 100 is the average. Your IQ therefore describes how you performed relative to others, not how many questions you got right.
This online test does not have a large reference group, so it converts your number of correct answers into an estimated IQ on a transparent scale. That makes it useful for practice and comparison over time, but it is not a substitute for a supervised assessment.
How accurate is an online IQ test?
Online IQ tests are good for fun, curiosity and practice, but they have real limits. A short, unsupervised test measures a narrow slice of thinking, and your score can be affected by tiredness, distraction, the device you use and the strategies you know. For any official purpose, such as education, employment or clinical decisions, only a qualified psychologist can give you a valid result.
How to prepare and improve your reasoning skills
- Learn common sequence rules. Look for steps, differences of differences, doubling, alternating patterns and special numbers such as squares and primes.
- Describe visual patterns in words. Ask what changes across each row and down each column: shape, fill, size, number or rotation.
- Read every question twice. Many mistakes come from missing a word such as “further” or “second”.
- Manage your time. With 25 minutes for 36 questions you have around 40 seconds each. Skip a stuck question rather than losing several others.
- Look after your brain. Sleep well, take the test somewhere quiet, and practise regularly.

IQ test FAQs
Is this IQ test accurate?
It is a short online test for interest and practice, so it cannot match a supervised, standardised assessment such as the Wechsler or Stanford-Binet scales given by a psychologist. Treat the score as an estimate of how you performed on these 36 reasoning questions.
How is the IQ score calculated on this test?
Each correct answer earns one point, and unanswered questions count as incorrect. Your points are converted to an estimated IQ on a simple scale that runs from 70 (no correct answers) through 100 (18 correct) up to 130 (all 36 correct).
What is a good IQ score?
On standardised IQ tests the average is 100. About two-thirds of people score between 85 and 115, scores of 110 to 119 are described as high average, and around 2 in 100 people score 130 or above.
What is the average IQ?
The average IQ is 100 by definition on most modern tests. Scores are set so that the typical person lands at 100, with a standard deviation of 15 points.
How long does the IQ test take?
You have 25 minutes to answer all 36 questions. If time runs out, the questions you have answered are scored and the rest count as incorrect. You can also pause with the exit button and resume later, and the clock stops while you are away.
What do the four sections measure?
Pattern reasoning uses visual matrices to test how well you spot rules in shapes. Number reasoning tests sequences and numerical rules. Logical reasoning tests deduction, analogies and coding. Applied reasoning tests practical problem solving with everyday maths.
Will the questions change if I retake the test?
Yes. The questions, numbers and answer options are randomised on every attempt. Retaking the test can still raise your score slightly, because you become familiar with the question types.
How can I improve my score?
Practise spotting rules in number sequences and visual patterns, read every question carefully, and keep an eye on the timer so that you do not spend too long on a single question. Sleep, focus and a quiet environment also make a difference.
Is the IQ test free and do I need to sign up?
Yes, it is completely free with no registration. The test runs in your browser, and your progress is saved only on your own device.
Can this test diagnose a learning difficulty or intellectual disability?
No. Only a qualified professional using a full clinical assessment can do that. If you have concerns, please speak to a doctor, a psychologist or an educational specialist.
This IQ test is provided for education and entertainment. The score is an estimate and is not a clinical or diagnostic result. If you have concerns about learning, memory or thinking, please speak to a qualified professional.
