This page is intended for measuring high IQ using numerical tests. While tests such as those used for qualifying for the Mensa community mainly focus on identifying the top 2% of the most intelligent people and generally do not measure above 145 (SD=15), the tests on this site are designed to measure IQ up to a level of 190 (SD=15).

News!! All my tests are now (since 03/08/2025) FREE to take until 01/01/2026.
