Free IQ Test with Instant Score

An IQ test question is a short reasoning problem built to measure pattern recognition rather than learned knowledge, which is why the same formats repeat everywhere: number series, verbal analogies, odd one out and logic chains. This quiz is a free, self scored practice set of 15 questions across those four formats, and it reports a score and a result tier as soon as you finish. It is not a clinical assessment. It produces no validated IQ number, uses no age norms or standardised sample, and should never be read as a diagnosis. What it does show is which question types slow you down. One series item asks what follows 1, 4, 9, 16, 25, and the answer is 36 because each term is a square. One trap item asks how long 100 machines need to make 100 toys when 6 machines make 6 toys in 6 minutes; the answer is still 6 minutes.
