Frequently asked questions
Is this test free?▼
Yes, the test is fully free — every question, the scoring and the result with a dimension-by-dimension interpretation. You see your result immediately after the last answer, with no registration, e-mail or card required. An extended PDF report is available as an optional purchase, but you do not need it to see and understand your score.
How long does it take to complete?▼
This test is timed: you get 25 minutes for 30 questions, and the countdown starts when you begin and stays visible throughout. When time runs out we score the answers you have given so far, so try not to get stuck on any single question. Avoid refreshing the page — the clock keeps running.
Are the results accurate?▼
The test is based on a published, validated psychometric instrument — the source and authors are listed in the scientific-basis section on this page, and clinical tests additionally cite their validation studies. Scores are computed with the published scoring keys. Bear in mind that a self-report questionnaire captures a snapshot in time and is educational — it does not replace a clinical diagnosis by a professional.
Can I save my results?▼
Yes. Right after the test you can save the result to a free account in one click — just an e-mail; sign-in uses a magic link, no password. Saved results build your psychological profile, where you can compare dimensions across different tests on one chart and revisit results any time. Without an account you still see your result — it just is not kept for later.
