    Frequently Asked Questions About IQ Tests

    What is an IQ test?

    An IQ test is a standardized assessment that measures cognitive abilities. It evaluates fluid reasoning, pattern recognition, spatial awareness, and problem-solving – producing a score normed to a mean of 100.

    How is an IQ score calculated?

    Your raw score is compared to population norms using a bell curve with mean 100 and standard deviation 15. This tells you exactly where you rank relative to the general population.

    What is a good IQ score?

    Average is 90–109. Scores of 120+ are superior (top 9%), and 130+ puts you in the top 2% – typically the threshold for Mensa membership.

    Can I improve my IQ score?

    While crystallized intelligence grows with learning, fluid intelligence can be trained through challenging cognitive exercises, adequate sleep, regular exercise, and a balanced diet.
