IQ scores follow a normal distribution. Most people score between 85 and 115.
The Science
An IQ score is a standardised measure of cognitive ability. Scores are calculated by comparing your performance to a reference population of the same age group, then placing it on a scale where 100 represents the population mean.
The standard deviation is 15 points. This means approximately 68% of people score between 85 and 115. Scores above 130 are achieved by roughly 2% of the population. Scores below 70 are equally rare.
This assessment maps your raw performance across 40 questions to this standard scale using a validated bell-curve formula — the same mathematical foundation used in clinical psychometric instruments.
Average IQ scores vary by country. Where do you stand relative to your national average?

“The spatial reasoning section genuinely challenged me. Most online tests feel like guessing games — this one actually made me think. My score was lower than I expected, which honestly made me trust it more.”

“I took this after trying brght and iqtest.net. The cognitive breakdown across 5 dimensions is what sold me — not just a single number but an actual profile of how my brain works.”

“Spent 19 minutes on it. The processing speed section with the 10-second timer was stressful but fun. Worth the unlock to see where I ranked against the population.”
