What your score means

Each correct answer earns one point. All questions have equal weight. The timer has no effect on your score. The result shows a raw count out of 40, with separate counts for the three question groups.

There is no standardized IQ score, age adjustment, population comparison or clinical interpretation. These questions have not undergone psychometric validation, and their ordering is editorial rather than an empirically calibrated difficulty scale.

Control over your progress

Answers stay in page memory unless you choose “Save progress in this tab.” That choice uses this browser tab’s session storage and can be switched off. Use “Clear answers” to remove the saved attempt. Closing the tab normally removes session storage; some browsers may restore it when restoring a session.

One challenge, two ways to begin

Both introductions lead to the same questions and scoring. The URL carries only the introduction choice. We do not send quiz answers or completion events to an analytics service.
