An IQ (Intelligence Quotient) test is a test that is used to determine people’s cognitive abilities, as well as assess people’s intellectual levels and potential. In fact, different IQ tests can help identify both mental subnormality and intellectual potential. The United States conducted the first official IQ tests ever in the early 1900s in order to assess schoolchildren’s intellectual abilities and patients’ mental health.
Our original IQ test features
We have developed a 40-question test to confidently use in different countries and get the most accurate results. The test excludes the cultural peculiarities of different countries and aims at assessing an individual’s intellectual potential.
The test was developed in such a way that, when completed, the results are generated using a normal distribution method with an average IQ equal to 100 and a standard deviation of σ = 15. Therefore, 2⁄3 of all the results (which is about 68%) range from 85 to 115.
The test has no time limits, but we recommend that you complete it within 20 minutes. That will maximize the test accuracy and help you discover your ability to quickly and accurately solve problems. If it takes you longer than 20 minutes to complete the test, your score will be lower.
On average, it should take you 15 seconds to solve easy questions, 35 seconds to solve medium ones, and one minute to answer the most difficult ones.

This is the highest attainable score when testing the intelligence level. We call such people geniuses. They have no trouble solving the IQ test. As a rule, they complete the test successfully faster than the specified time. Many people with similar IQ levels achieve significant success in various areas of life. Such people comprise about 2.2% of the population. Even fewer people can get the highest results exceeding 145 points. For instance, there are only 0.2% of people in the world that are capable of getting this score.
121 to 130 IQ points
This is a rather high result of the IQ test. We often call such people gifted. They can answer easy, mid-level, and most difficult questions with no problem.
111 to 120 IQ points
This is the upper margin of the average result, which is good for many people. As a rule, they can answer easy to mid-level questions with no problem. However, they may have a harder time with difficult ones.
Average IQ classification
90 to 110 IQ points
This is the average IQ level for an individual. More than 50% of all people have intellectual abilities within these limits.
Low IQ classification
80 to 89 IQ points
This is the lower margin of the average result. This result is normal for many people. As a rule, they answer easy questions with no problem. They can also solve mid-level questions but may make mistakes due to poor attention or a lapse of concentration. As a rule, this test-taker skips the more difficult questions or takes too much time to answer them.
66 to 79 IQ points
This is a lower margin of a poor result showing that an individual has problems with attention, memory, and reasoning, as well as difficulties in solving mathematical and logical problems. Nevertheless, an individual like this is still capable of leading an independent lifestyle and solving daily problems the way most people do.
65 IQ points or less
All the results below 65 points are extremely low and mean that an IQ test-taker manifests mental retardation. As a rule, most people like this cannot live on their own and have difficulties with everyday tasks.
Questions: how many should you answer?
A range of 30 to 50 questions should suffice for real IQ testing. Fewer questions will not allow for accurate intelligence level assessment.
Therefore, some popular online IQ tests consisting of 3, 5, or 10 questions cannot assess an intelligence level accurately.
More than 50 questions will increase test duration, entailing a further lapse of concentration. So, the optimal number of questions is from 30 to 50.
