Yes, but we recommend waiting at least 6 months between attempts. IQ tests have a "practice effect"—taking the same test multiple times can artificially inflate your score. For the most accurate results, treat each attempt as if it's your only one.
The average IQ score is 100, with most people (68%) scoring between 85-115. A score of 115-130 is considered above average, 130-145 is gifted, and 145+ is highly gifted. However, IQ is just one measure of intelligence—creativity, emotional intelligence, and practical skills matter too.
While core cognitive ability is relatively stable, you can improve specific skills through practice. Brain training, learning new skills, reading, and solving puzzles can enhance pattern recognition, processing speed, and problem-solving abilities. Most people see modest improvements (5-10 points) with consistent cognitive training.
No registration required to take the test! You can start immediately and get your basic results without providing any personal information. If you want to save your results or receive a certificate, you'll need to provide an email address—but that's completely optional.
Our test is designed for adults (18+) and older teenagers (16-17). For younger children, specialized age-appropriate IQ tests are more accurate. IQ scores are age-normalized, meaning your score compares you to others in your age group.
