One common thing that all IQ tests attempt to find is the g score. It stands for general intelligence, a measure of a person’s mental capacity and ability. In psychometrics, the “general intelligence factor” predicts someone’s success in life by assessing their ability to solve problems. Modern IQ tests in schools and large organizations now strive to be more cognizant of cultural biases and family background. Nonetheless, it’s essential to remember that an IQ score, while insightful, isn’t an absolute measure of one’s intelligence.

If a 10-year-old performed at the level of a typical 12-year-old, their mental age would be 12. An IQ Test, or Intelligence test, is a series of questions and problems that seek to find the general intelligence of the participant. The quiz has many formats, from identifying similar images to predicting sequences.

Comprehensive tests will usually incorporate both aspects, and if a test only includes one element over another, the results should be adjusted. This is why an average IQ score is said to be 100 because this means that a person’s mental age is the same as their actual age. Psychologists distinguish two broad components of general intelligence. Fluid intelligence (Gf) is the capacity to reason through novel problems — spotting patterns, drawing inferences, and thinking abstractly without relying on prior knowledge.

Whether you’re looking to challenge yourself, practice for an official IQ test, or simply explore your cognitive abilities, IQtest-free.org is your go-to resource. It depends on what you mean by ‘good.’ A score of 100 is perfectly average, and most people fall between 85 and 115. Scores above 120 are considered superior and place you in roughly the top 10% of the population. But fixating on a number misses the point — the most useful thing about an IQ test is understanding your cognitive profile, not chasing a particular threshold. Clinical tests like the WAIS-IV and Stanford-Binet are administered one-on-one by a trained psychologist and take 60–90 minutes.

However, the original Binet-Simon scale underwent several modifications and adaptations, especially when introduced to the United States. Lewis Terman, a psychologist from Stanford University, was instrumental in refining and standardizing this test, resulting in the Stanford-Binet Intelligence Scales. Terman introduced the “Intelligence Quotient” or IQ, calculated as (Mental Age/Chronological Age) x 100. One player has achieved a full score of 50 during the time that the test has been running.

It refers to an individual’s performance in relation to the score of others in the entire population. The average IQ score is set at 100, with a standard deviation of 15. This means that the majority of the population falls within one standard deviation of the average, so scores between 85 and 115 are considered within the normal range. A score of 85–115 (25th–75th percentile) reflects average cognitive ability.
