Frequently Asked Questions About IQ Tests
Have other questions? Please contact us via email.
Can an IQ test accurately measure my intelligence?
IQ tests are effective tools for measuring cognitive abilities, but they only measure specific types of intelligence. Our tests are based on recognized psychometric standards and provide relatively accurate intelligence assessments, but should be combined with other factors to comprehensively understand individual abilities.
How long does it take to complete the test?
Our standard IQ test takes about 10-20 minutes to complete. The test has a time limit, which is an important part of the assessment process. Please ensure you have enough uninterrupted time before starting the test.
How can I get a detailed test report?
After completing the test, you will immediately receive a basic IQ score and brief analysis. For a detailed personalized report, including cognitive strength analysis and development suggestions, you can upgrade to our premium version.
Do IQ scores change over time?
IQ scores are relatively stable after adulthood but may be influenced by various factors such as health conditions, educational experiences, and environmental changes. Regular testing can help track changes in cognitive abilities.
Will my test results be kept confidential?
Yes, we take user privacy very seriously. Your test results and personal information are strictly protected and will not be shared with any third party without your explicit permission.
Can I take the test multiple times?
You can take the test multiple times, but please note that familiarity with the test content may affect results. We recommend spacing different tests at least 3-6 months apart to get the most accurate assessment.
