The IQ test score takes one’s age, the number of correct answers and the completion time into consideration for the ranking. After that, a so-called percent rank (from 0-1) is calculated and normalized with the bell curve (mean 100 and deviation 15) in order to calculate the IQ score. This IQ score is dynamic and can change over time, as more and more people take this IQ test your percent rank can change. Once you completed your test you can visit your result page and see your score change and adjust in real-time. The score won’t change significantly because over 250,000 people have taken this test already.

It measures cognitive abilities, including reasoning, problem-solving, memory, and other aspects of intelligence. A score of 85–115 (25th–75th percentile) reflects average cognitive ability.

IQ tests measure a specific set of cognitive abilities — reasoning, pattern recognition, working memory — that psychologists call ‘g’ or general intelligence.

The threshold is identical across countries; only the scale label changes. This IQ test consists of 50 multiple choice questions that are all abstract in nature. Your answers will be ranked against other scores gathered in a carefully conducted baseline study.
