Frequently asked questions
A few useful answers.
Updated 1 November 2026
Is this a standardized IQ test?
No. This is a reasoning exercise. Your result is the number of correct answers out of 25, not an IQ score or a clinical assessment.
How many questions will I answer?
Each attempt draws 25 different questions from a bank of 100. Different attempts may share questions. The question order and answer order are shuffled.
How much time do I have?
Twenty minutes from the start of your attempt. The server’s timer keeps running if you leave the page.
Can I go back to earlier questions?
Yes. Use Previous, Next or the question-number grid. You can change answers until you submit or time runs out.
What happens if I lose my connection?
Keep the page open and reconnect. Choices are retried while the page remains open. Only choices saved on the server can be restored after a reload. If time expires, only answers saved before the deadline count.
Do I need to pay?
Taking the test is free. Results are locked when you finish. This preview offers an explicitly labelled free demo unlock. Planned $1.39 one-time paid access has not launched. There are no subscriptions or automatic renewals.
Can I download a certificate?
After using the free demo unlock, you can download a text result summary. This is not an official IQ certification.
Why does the site show my country?
A local IP-to-country database estimates the country of your network connection. It does not use GPS and may show a VPN or proxy location. No national average IQ is inferred.
Can I remove my attempt?
Yes. The support page has a control to delete the current browser’s attempt. Clearing cookies alone does not remove a server record.
How can I report a problem?

Language preference
We store your manual language choice in an essential cookie for up to one year. Without a saved choice, a Vietnamese IP selects Vietnamese; other or unknown countries select English. Changing language does not change your questions, answers or deadline.
How do I change language?
Use VI / EN on any page or in the opening popup. Your choice is remembered in this browser and takes priority over IP detection.
