How the test is built
Every IQ test on Wittoria is generated fresh when you start it.
Questions come from four kinds of reasoning: pattern grids, number sequences, verbal logic and spatial puzzles.
The order of questions and answers is shuffled, so no two runs are the same.
How your score is worked out
Your answers are scored on our server, and the answer key never reaches your browser.
Scores use the classic IQ scale, where the average is 100 and the standard deviation is 15.
The Standard test runs from 65 to 180. The Hard and Extreme tiers score up to 190.
A 15-minute timer runs on our server, so the clock cannot be paused from the page.

What it is not
An online test is an estimate for curiosity and self-reflection.
It is not a clinical, diagnostic or professional assessment.
For a formal IQ assessment, see a qualified psychologist.
