Find out your real IQ.

IQScore uses 36 questions drawn from established cognitive assessment frameworks covering spatial, numerical, logical, and applied reasoning. Your performance is mapped onto the standard IQ scale (mean 100, standard deviation 15) to produce an estimated score. While not a clinical assessment, it gives a useful estimate of your cognitive ability.

The test consists of 36 questions with a single 25-minute total time limit. Work at your own pace, the timer runs continuously across all questions. Most people finish well within the time. If the timer reaches zero, whatever answers you have given are submitted automatically.

Yes, completely optional. Your IQ score, percentile and four-domain breakdown are free and complete on their own, with nothing held back. The report is simply for people who want to go deeper: it shows the correct answer to every question, a detailed look at your strengths and weaknesses across the four domains, a full 8-section cognitive analysis, and a downloadable PDF certificate. There is no obligation to buy it, and plenty of people never do. For those who want it, it is a single one-time payment of $4.99.

No. The report is a single one-time payment of $4.99, you are charged once and never again. IQScore has no subscriptions and no recurring billing anywhere on the site, and we never will. We know online IQ tests have a reputation for surprise charges, so being completely upfront about this matters to us.

Online IQ estimates carry a standard margin of ±7–10 points, a measurement reality that applies to all uncontrolled testing environments, including premium-priced competitors. For a clinically validated result recognised for academic or legal purposes, consult a licensed psychologist. IQScore gives you a reliable baseline for personal insight.
