IQ tests are free with unlimited attempts. The same four question sets repeat; only first-time results are eligible for public ranking.

All IQ tests, results, analyses and certificates are free. You can retake the same four existing question sets as often as you wish. Repeated scores do not qualify for the public leaderboard.

Your IQ score is a provisional estimate, not an independently normed test or clinical diagnosis. Your full report and certificate are free.

Eligible unlocked 30-question results enter the leaderboard after publication preferences are recorded. Each person appears once with their highest eligible estimated score; a shorter completion time breaks ties. Time is not displayed. A lower new result does not replace your best one.

Open Account and choose Edit profile. You can change your display name and upload a JPEG, PNG or WebP image up to 2 MB. Your Google account name is not changed. A saved profile photo can also be removed.
