Standard 100 ± 15 scale
Your score sits on the classic scale (mean 100, standard deviation 15), the same standardization the major intelligence tests use.
Four reasoning dimensions
Fluid reasoning, verbal comprehension, visual-spatial and quantitative reasoning — the same cognitive indices the reference psychometric batteries measure.
Difficulty-calibrated items
Every question is classified by domain and difficulty and human-reviewed before it goes live.
Percentile from the bell curve
Your percentile is derived from the normal distribution — a real statistical ranking, not an invented number.
Methodology inspired by reference psychometric batteries and classical test theory. Orientative, for self-knowledge — not a clinical diagnosis.

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.
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.
