How does an online IQ test work?
You answer 20-40 reasoning questions — usually visual patterns, sequences and logic puzzles. Behind the scenes, your answers are compared to a standard scale where 100 is average and the population follows a bell curve with a standard deviation of 15.
Is an online IQ test accurate?
A well-built online test is a solid estimate of your reasoning ability, but not a clinical IQ score. Formal scores (for Mensa, gifted-programme placement or diagnosis) require a proctored, standardized test with a licensed psychologist.

How to take an IQ test online for the most accurate result
- Pick a quiet moment. Rested, focused and undisturbed matters more than time of day.
- Do not look up answers. The estimate is only useful if it is honest.
- Answer at a steady pace. Do not linger; if unsure, pick the most obvious pattern and continue.
- Take each test only once. Familiarity inflates repeat scores.

What is a good IQ score online?
