How does the IQ test work?
You solve a series of puzzles. Each one is a grid of shapes with one piece missing, and you pick the piece that completes it. They start easy and get harder. You don’t need to read or do sums.
What does my result show?
Your IQ and your percentile. The percentile is the share of people you scored higher than: an IQ of 115 is higher than 84% of people.
How is my IQ worked out?
Your answers are scored and placed on the IQ scale, where the average is 100 and the standard deviation is 15. Your percentile comes from the same scale, so it is the same number the certificate shows.
What is a good IQ score?
100 is the average. Two thirds of people score between 85 and 115. A score of 115 is higher than 84% of people, and 130 is higher than 98%.
How does the certificate work?
Every certificate has its own 12-character code, printed on it. Anyone can enter the code on our lookup page to see the name, IQ and date on that certificate.
Is this a clinical IQ test?
No. It is an online test. Clinical IQ tests are given in person by a psychologist.
How often can I retake the IQ test?
In the app, the next IQ test opens 14 days after your last one, once you have played 10 training games in the last 14 days. The next test is never the one you just took.
What is a percentile?
Your percentile is the share of people you scored higher than. The 90th percentile means a higher score than 90 of every 100 people. You can turn any IQ into a percentile with our calculator.
