Jordan Stevenson

“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.”

Sandra Bennett

“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.”
