What this test measures

Our IQ test uses Raven's Progressive Matrices-style visual puzzles, numerical series, logical deduction, and verbal analogies — the same cognitive domains used in professional assessments (Wechsler, Stanford-Binet). Results are normalised to mean 100 / SD 15. 30 questions, typically completed in 8–15 minutes.

Is this IQ test accurate?

Our test uses Raven's Progressive Matrices-style visual puzzles, number series, verbal analogies and logical deduction — the same cognitive domains used in clinically validated IQ assessments. Results are normalised to mean 100 / SD 15. It's an excellent self-assessment tool, though not a certified clinical instrument.

How long does the IQ test take?

30 questions, typically 8–15 minutes. Speed is factored into your score — faster correct answers earn a small bonus. The time limit is 30 minutes.

What is a good IQ score?

IQ follows a bell curve: 100 is average. Scores above 130 place you in the top 2% (Mensa range). 110–130 is High Average to Superior. 90–110 is Average. Each session draws fresh random questions so retakes remain valid.

What cognitive areas does this test cover?

Four domains: (1) Pattern Recognition — Raven's matrix puzzles, rotation sequences; (2) Logical Reasoning — syllogisms, analogies; (3) Mathematical Reasoning — number series, probability, algebra; (4) General Knowledge. Your results include a colour-coded breakdown per domain.

Can I retake the IQ test?

Yes — each session randomly selects 30 non-repeating questions from a pool of 130+, so you'll encounter different questions every time.
