Test your logic, verbal reasoning, and problem-solving skills. Find out how you compare to the population.
The adaptive version adjusts difficulty to your answers — a shorter test with more accurate results.
The test measures three key components of cognitive ability.
Get an estimate of your IQ based on 40 questions testing various cognitive abilities. The average population IQ is 100.
Discover which areas you excel in — numerical intelligence, verbal reasoning, or logical thinking.
See how you compare to the general population — which percentile you fall into.
The test contains 40 questions with a 20-minute time limit. For each one, you choose the correct answer from four options. Difficulty gradually increases.
Based on the number of correct answers and question types, we calculate your IQ score and identify the strengths of your cognitive profile.
You'll see your IQ score, percentile ranking, cognitive profile, and population comparison.
The test measures three key areas of cognitive ability.
Basic results are completely free. The extended version reveals your complete cognitive profile.
IQ (Intelligence Quotient) is a standardized measure of cognitive abilities. The average population IQ is 100 with a standard deviation of 15 points — meaning approximately 68% of people have an IQ between 85 and 115.
Our test is inspired by ICAR (International Cognitive Ability Resource), a freely available and psychometrically validated tool developed by researchers at Northwestern University. ICAR correlates with classic IQ tests (e.g. WAIS) at a level of r = 0.81.
The test measures three main components of cognitive ability: numerical intelligence (recognizing patterns in number series), verbal intelligence (understanding relationships between concepts), and logical thinking (deduction and problem solving).
An IQ test is not a measure of your worth or success — it is one of many tools for understanding your own cognitive strengths.
The test measures three key cognitive abilities: numerical intelligence (working with numbers and patterns), verbal reasoning (understanding relationships between concepts), and logical thinking (deduction and problem solving).
The test is inspired by ICAR (International Cognitive Ability Resource), a validated research tool. It provides an approximate IQ estimate, not a clinical diagnosis. For precise measurement, we recommend visiting a psychologist.
The time limit (20 minutes) is a standard part of IQ tests. It measures not only accuracy but also the speed of cognitive processing. Most people are able to answer all questions in time.
Yes, you can retake the test at any time. However, keep in mind that repeating the test can artificially inflate your score because you remember the questions. For the most accurate result, the first attempt is best.
The average IQ is 100. A score of 115+ is above average (top 16% of the population). A score of 130+ is exceptional (top 2%). However, there is no "good" or "bad" IQ — everyone has different cognitive strengths.
