Frequently Asked Questions

Can you explain the difference between the free and paid IQ test?

The free IQ test is a quick, fun way to estimate your IQ with 10 fixed questions. It’s great for a general idea, but not as precise.

The full IQ test, however, is much more advanced. It adapts to your skill level, includes 25 carefully designed questions, and provides a far more accurate result. Plus, you’ll get access to detailed analytics, extra retakes, and even a certified IQ certificate!

How long does the IQ test take?

The free IQ test takes around 10 minutes, but there’s no time limit—you can go at your own pace.

The full IQ test is designed to take up to 25 minutes, and the time is limited to keep the challenge accurate.

Which IQ test is the most accurate?

Our full IQ test is the most accurate. It uses 25 adaptive questions, meaning the difficulty adjusts to your responses in real time, giving a more precise IQ score. This is the same methodology used in official cognitive assessments.

Do you offer other plans?

Yes! We offer additional plans with extra features, including:
  • More retake options to improve your score
  • Official QR-verified certificate
  • Personalized link to showcase your highest IQ score
  • Advanced cognitive analytics with deeper insights
  • Ability to compare your IQ with friends
You can explore these options after completing the full IQ test.

Can I access CheckIQ on any device?

Yes! You can take the test on any device—mobile, tablet, or desktop. Everything is optimized for a smooth experience.

Paid users also get access to a secure dashboard where they can track their IQ scores, review results, and retake tests anytime.
