Average IQ by country
An IQ (Intelligence Quotient) test is a test that allows determining people’s cognitive abilities, as well as assessing people’s intellectual level and potential. Actually, different IQ tests can equally help identify mental subnormality and intellectual potential. First Official IQ tests ever were conducted in the United States in the early 1900s to assess schoolchildren’s intellectual abilities and patient’s mental health.
Our online IQ test features
We have developed a 40-question test to confidently use it 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 manner that, when completed, the results are generated using a normal distribution method with an average IQ = 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 you complete it within 20 minutes. That will maximize the test accuracy and help you find out 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.

High IQ classification
IQ points 131 and more
That is the highest level obtainable when testing the intelligence level. We call such people geniuses. They have no trouble solving the IQ test. As a rule, they can cope with the test sooner than the time specified. Many people with similar IQ levels achieve significant success in various life areas. There are about 2.2% of such people. Even fewer people can get the highest results exceeding 145 points. For instance, there are only 0.2% of people capable of getting this score.
IQ points 121 to 130
That 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.
IQ points 111 to 120
That is the upper margin of the average result, which is good for people. As a rule, they can answer easy to mid-level questions with no problem. However, they may have a hard time with difficult ones.
Average IQ classification
IQ points 90 to 110
That is the average IQ level for an individual. More than 50% of all people have intellectual abilities within these limits.
Low IQ classification
IQ points 80 to 89
That is the lower margin of the average result. This result is normal for people. As a rule, they answer easy questions with no problem. They can also cope with mid-level questions but may make mistakes due to poor attention or a lapse of concentration. As a rule, a test-taker skips more difficult questions or takes too much time to answer them.
IQ points 66 to 79
That is a lower margin of a poor result showing that an individual has problems with attention, memory, 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.
IQ points 65 and lower
All the results below 65 points are extremely low and mean that an IQ test-taker manifests mental retardation. As a rule, the people like these cannot live on their own and have difficulties with everyday tasks.
IQ test 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.
