Frequently asked questions
Are Aptenna tests real IQ or psychological tests?
No. Aptenna tests are designed for educational and entertainment purposes. They are not clinical, medical, or professionally administered assessments, and results should not be treated as official diagnoses or scores.
Do I need to create an account?
No. Every test can be taken without signing up. If you retake a test, your personal best and streak are stored locally in your browser, not on a server.
How is my score calculated?
Each test scores your answers against a weighted question bank and shows a category-by-category breakdown. Our Testing Methodology page explains the exact approach for each test.
Can I retake a test?
Yes, any time. Many tests draw from a larger question pool, so a retake isn't always identical to your first attempt.
