Methodology: How this test works
What it measures: Built on item formats established in cognitive science, the test has 30 questions across four areas — logical reasoning, spatial perception, numerical processing and verbal comprehension. Through matrix reasoning, number series, figure rotation and more, it gauges pattern recognition, logical thinking, spatial awareness and processing speed.
Scoring: Each question has a time limit, and answers are weighted by difficulty (easy, medium, hard). Your overall score rate is mapped to a deviation-IQ scale centered on 100.
Refinement: We continuously review the difficulty balance and score conversion using data from more than 100,000 test takers.
What it is: This is an online estimate for educational and self-understanding purposes. Unlike standardized clinical assessments such as the WAIS administered by a licensed psychologist, the result should be used as a guideline.
