How scoring works

The final score is calculated by projecting your correct answers onto the normal distribution curve. Each area contributes to your Unified Cognitive Profile.

  • The test has 20 questions ordered by increasing or mixed difficulty.
  • You have exactly 20 minutes. Unanswered questions count as wrong.
  • You can move freely back and forth between questions before submitting the final test.
  • We recommend taking the test in a quiet room, without distractions and without search engines or calculators, to maximize accuracy.

The test is inspired by the standards used by major companies, but it is not a clinical tool and does not replace a professional neuropsychological assessment.

The test is free and you can share your generic result on social media (e.g. IQ 110–119, Above average, Top ~25%).

To get the certificate with your exact score (e.g. 117), the unique code and the verification links, a one-time payment of $2.99 is required at the end of the test. It's optional — you can take the test for free and there's no subscription.

Take the test and get your detailed result and a certificate you can share on LinkedIn and all social networks.
