Frequently asked questions
Is the test free?+
Yes. Taking the test and seeing your estimated IQ with your percentile is completely free. The full report, with the per-area breakdown and certificate, is an optional one-time purchase.
Do I need to sign up or give an email address?+
No. There is no account, no registration and no email required: you answer the 20 questions and your IQ score and percentile appear on screen straight away. An email only comes into it if you choose to buy the full report, and it is the payment provider that collects it.
How long does it take?+
Most people finish in about 15 minutes. The hard limit is 20 minutes, and time is part of the measurement.
Is this an official diagnosis?+
No. It is an orientative test for self-knowledge. It is not a clinical instrument and does not replace a professional assessment by a qualified psychologist.
Is there a subscription or recurring charge?+
No — never. The full report is a single one-time payment. No subscription, no auto-renewal, no hidden fees. You pay once and it's yours to keep.
