Methodology

YZR uses 40 items across pattern puzzles, number puzzles, word puzzles, shape puzzles, look and recall, and timed puzzles. Scoring maps weighted accuracy to an estimated IQ (mean 100, SD 15).

The margin printed with a result is provisional, about ±8 points, and may be wider. A free preview may show a coarse bracket that hides the exact number. That bracket is not a second margin.

This is an estimate on a standard scale (mean 100, standard deviation 15). It was not measured on a sample of YZR users. The margin is provisional, about ±8 points, and may be wider. It is not a clinical or diagnostic test.

The number is calculated from the share of puzzles you answered correctly, using a fixed formula. It has not been checked against other IQ tests.

Any summary issued here is issued by the platform. It is for entertainment and curiosity. It has no clinical, professional, or academic validity, and it is not an official IQ certificate.
