Common questions
Is this IQ test scientifically valid?
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.
How long does the test take?
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.
Do I need to create an account?
No. Your IQ score is completely free, no registration, no email required. The optional paid extras use Stripe for payment but require no account creation either.
Are there any paid options, and what do they include?
Yes, and it is completely optional. Your IQ score, percentile and four-domain breakdown are free and complete on their own, with nothing held back. There is exactly one thing to buy: the IQScore Pack at $6.99, a single payment that includes a personalised certificate with your name and score, a full written report on your cognitive profile, and every one of the 36 questions explained with the correct answer. That is the only purchase on the site, there is nothing after it, and plenty of people never buy it at all. You can inspect the whole product before deciding — a sample certificate, a report extract and two fully explained answers are at iqscore.io/sample.
Are there any hidden fees, recurring charges, or subscriptions?
No. The IQScore Pack is a single one-time payment of $6.99, charged once and never again, and it is the only purchase on the site. IQScore has no subscriptions and no recurring billing anywhere, and we never will. We know online IQ tests have a reputation for surprise charges, so being completely upfront about this matters to us: one payment, everything included, nothing afterwards.
How accurate is the score?
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.
25 minutes from now, you’ll know exactly where you stand.
