“Every two years or so I like to put my IQ to the test. So far I have increased it significantly for the last 6 years. This IQ test provides a good variety of tests to challenge the cortex to its utmost and the result is a summary of very clear and detailed descriptions of how each facet of intelligence is applied and expressed. I would recommend this test to anyone who wants to discover the capacity of their little grey cells.”

Micheal Rohan

United States

“A bit too expensive, and the results not close to a professional IQ test I took some years back. But the results gave some good overview and details, and the test tests more visual and spacial IQ, rather than the standard tests, which was refreshing.”

Lashaunda Chmura

Switzerland

“I enjoy taking these rather challenging tests! It helps me to build my confidence and faith within me and encourages me to take on more challenging tests!”

Noah Remley

“The IQ score is the headline result that you want, but the report that is also provided which breaks down the five aspects of human intelligence is very interesting. Worth the investment if you are looking to gain insights about yourself and use it in conjunction.”

“When I heard from my mom, I heard something ridiculous that my IQ, when I was young, was about 130. Of course I couldn't believe that so I just wanted to test my real IQ.”

Angela Valverde
