This method provides more reliable and valid IQ scores across a wide age range.
If you are interested in knowing your IQ, it is recommended to take a professionally administered and standardized IQ test. These tests provide a more accurate and comprehensive assessment of cognitive abilities, taking into account various factors that influence intelligence. Keep in mind that IQ tests are just one aspect of measuring a person's abilities, and intelligence is a complex and multifaceted trait that cannot be fully captured by a single test score.
