What is an IQ test?
An IQ test is a set of reasoning problems whose results are converted into a score that compares you with other people. On the standard scale the average is 100, and about two thirds of people score between 85 and 115. Most IQ tests combine different kinds of question, such as pattern puzzles, number sequences, word relationships and logic, because intelligence is not one single skill.

- Logical reasoning
- Working out what must be true from the facts given, including multi-step deductions and puzzles with contradictions.
Online IQ test or professional IQ test?
An online test like this one is quick, free and good for curiosity and self-insight. A professional test is given one-to-one by a psychologist, takes an hour or more and is standardised on thousands of people, which makes it the right choice for educational, clinical or official purposes.

How accurate is this free IQ test?
Honest answer: it is a screening estimate. Twenty-four questions cannot match a supervised professional assessment standardised on thousands of people. We show a likely range of about 11 points either way, we correct for guessing, and we flag results that look unreliable, such as rushing or skipping many questions.

What is a good IQ score?
IQ scores are set so that the average is 100. About half of people score between 90 and 109, and about 2 in 100 score 130 or above. See the IQ score chart for every range.
What IQ score do you need for Mensa?
Mensa membership requires a score at or above the 98th percentile on an approved, supervised test. On a scale with a standard deviation of 15 that is roughly an IQ of 130, although the exact number depends on the test. An online estimate cannot qualify you.
What does the IQ test measure?
Four reasoning skills: pattern reasoning with shapes, number sequences, verbal reasoning with word relationships, and logical reasoning. Each skill is scored separately so you can see your profile, not just one number.
Can I take the IQ test on my phone?
Yes. The test is designed for phones, tablets and computers, works in any modern browser and can be installed like an app. Use a quiet place and avoid interruptions for the most accurate result.
Do you store my answers or personal data?
No account or email is needed. Your answers and results stay in your browser on your own device so you can resume and view your report. They are not sent to our servers.
Can children take this test?
It is designed for ages 16 and over and is not age-adjusted, so scores for children would not be meaningful. For a child, ask a qualified educational or clinical psychologist.
Can I retake the test to improve my score?
You can, but the questions stay the same, so retaking soon mostly measures your memory of them. Wait at least four weeks, and use the practice tips in your report in between.
Ready? It takes about 20 minutes.
Find a quiet spot, put your phone on silent and give it your full attention.
