How the test works
Twenty-five items, five cognitive categories, twelve minutes, and one immediate composite score.
The format
You will see a sequence of 25 multiple-choice items, drawn evenly from five cognitive categories: pattern recognition (Raven-style matrices), numerical reasoning (series and proportions), verbal reasoning (analogies and semantic relationships), spatial reasoning (mental rotation of solids), and logical deduction (syllogisms and conditional reasoning). Each item has exactly one defensible correct answer.
The timing
There is no per-question timer on the free test. We recommend giving yourself about twelve minutes total, but the score does not penalize you for taking longer. If you are practicing for a timed assessment elsewhere, you can self-time using a stopwatch and aim for thirty seconds per item.
The scoring
Each correct answer contributes equally to a raw score. The raw score is then mapped through a normative table to a scaled IQ score with a mean of 100 and a standard deviation of 15. This is the standard scaling used by virtually every modern IQ instrument including the WAIS, WISC, and Stanford-Binet, so your score on this test is roughly comparable in interpretation, even though the underlying item set is shorter.
The category breakdown
Alongside the composite, you will receive a percent-correct figure for each of the five categories. The breakdown is informational, not normative — it tells you where your reasoning was strongest in this sitting, but it should not be over-interpreted from a single short test. If a category is unusually low or high relative to your composite, retake the test in a week to check whether the pattern is stable.
Privacy
The test runs in your browser. We do not require an account or an email address. Your answers and your score are not stored on our servers; they live in your URL after you finish, which means you can bookmark a result page if you want a record. If you close the tab without bookmarking, the result is gone.
When to take a real assessment
If you need a clinical-grade IQ score for a diagnostic purpose, an academic accommodation, or a legal matter, take a supervised, full-length test administered by a licensed psychologist. Online tests are excellent for self-knowledge and curiosity; they are not a substitute for a clinical assessment.
