How it works
Test. Report. Training.
MentalClarity measures how you reason, shows you exactly where you stand, and gives you a structured way to train the skills behind the score.
Take the test
36 non-verbal reasoning puzzles — matrices, series, rotations and logic — in about 20 minutes. No language knowledge needed, and the test itself is free.
Unlock your report
Your answers are scored on the standard deviation-IQ scale (mean 100, SD 15). The report shows your score, percentile, classification and a breakdown across the four reasoning categories.
Train your brain
Your report identifies your weakest categories and builds a personal training program from our games, puzzles and chess. Track your progress over time on your own dashboard.
Common questions
Is this a clinical IQ test?
No. MentalClarity provides an estimate of non-verbal logical reasoning under unsupervised conditions. It must not be used for medical, educational, professional or legal decisions.
How is the score calculated?
Each of the 36 items is weighted by difficulty. Your weighted score is converted to a z-score and then to the standard IQ scale (100 + 15z) with a percentile rank. Details are on the Method page.
What does the subscription include?
The full IQ report, a personalised brain training program, all games and puzzles, chess, e-books, and your progress dashboard. See the Pricing page for current prices.
Can I cancel?
Yes, at any time from your dashboard. Cancellation stops future charges and you keep access until the end of the paid period.
