All IQ tests are not equal. The only real IQ tests must be administrated and proctored by a professional, and can take many hours to complete. Most computer/internet IQ tests cannot be proctored and are made up by people who don't specialize in the field, and can be completed in half an hour or less. They tend to test things like grammar, spelling, vocabulary, math, and trivia instead of basic reasoning skills. And online IQ tests tend to give everyone higher scores than the real tests.
