Take a standardized IQ test administered by a licensed psychologist
Use a reputable, professionally normed online IQ test as a rough estimate
Compare your score to the test’s average of 100 and standard deviation of 15
Review percentile rankings to see how your score compares with others
Check whether the test measures verbal, spatial, memory, and reasoning abilities
Ensure the test was taken under controlled conditions without distractions
Repeat testing only after a long interval if you want a more reliable result
Avoid relying on unverified quizzes or social media tests
Ask a psychologist or testing center for an official interpretation of your score
