Fluid reasoning, verbal comprehension, visual-spatial and quantitative reasoning — the same cognitive indices the reference psychometric batteries measure.

Every question is classified by domain and difficulty and human-reviewed before it goes live.
Percentile from the bell curve

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.
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.
How is my IQ calculated?+
Your raw score is converted to the standard IQ scale (mean 100, standard deviation 15) using our statistical norms, which are recalibrated as more people complete the test.
Can I retake the test?+
Yes. Questions are drawn from a larger bank, so each attempt can vary. Keep in mind that retaking it many times in a row can inflate your result.
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.
