# IQ Atlas

> Take a free, scientifically structured IQ test in six language-free sections: pattern recognition, logic, numbers, spatial reasoning, memory and speed. Get your IQ score, percentile and represent your country on the world IQ map.

- Free: the full test, detailed results, the shareable result link and the Genius Test cost nothing.
- Language-free: every question uses only shapes, numbers and patterns, so the test is the same in every country.
- Six sections of 12 questions each (72 in total): pattern recognition, logical reasoning, numerical reasoning, spatial reasoning, working memory and processing speed.
- Takes about 45 minutes in total; sections can be taken separately, on different days, and each can be taken once.
- Scored with item response theory on the standard IQ scale (mean 100, standard deviation 15) and adjusted for age.
- Results give an IQ score, percentile, intelligence category and a per-section breakdown, and count anonymously towards the country's average on the world IQ map.
- The Genius Test unlocks with at least 70 of 72 correct answers and an IQ above 140, and measures the 140–165 range.
- The result is an estimate for personal insight, not a clinical assessment: the test is unsupervised and its norms are still being calibrated.
