This assessment covers seven cognitive domains: logical reasoning, pattern recognition, verbal intelligence, numerical ability, spatial reasoning, working memory, and processing speed.
Each domain contributes a weighted sub-score. Your final IQ is calculated using a normed composite formula aligned with Wechsler and Cattell–Horn–Carroll models. Each question has a per-item difficulty weight and a time-efficiency bonus.
Questions and answer order are drawn at random from a larger item bank each time you take the test, so retakes will differ.

Methodology: Scores are derived from a weighted composite of seven cognitive sub-scales, standardised to a mean of 100 and standard deviation of 15 (Wechsler scale). Fluid intelligence (pattern recognition, logical, spatial) accounts for 55 % of the composite; crystallised intelligence (verbal, numerical) 30 %; and processing efficiency (memory, speed) 15 %. This is an indicative assessment; certified IQ tests require clinical administration.
