I've used the test a couple of times it's structured perfectly and challenging in a good way. Really easy to use and complete the feedback afterwards is also really insightful. Sent an email regarding one of the test and the team replied which is a major green flag overall no gimmicks just straight to the point. I've bought 2 of the test results for personal reasons. Highly recommended if you're serious about understanding parts of your brain.

Outstanding Best testing experience I've ever had, with any online personality or intelligence assessments, the dashboard feature is incredible, and the support staff is quick and responsive.

The only place in the world to find inexpensive, and even free, scientifically accurate measurements of your cognitive ability. Truly a wonderful group of people doing incredible work.

Fun IQ tests that measure different abilities. Your scores may vary for all kinds of different reasons, but it's an interesting way of considering where your strengths may be and gives you a fairly robust ballpark estimate on an overall level of your IQ. I've only done CORE which is free, but I very much enjoyed it and highly recommend for those who are curious

Better than your standard online IQ test. Having multiple tests for different categories is nice.
