The problems found on an IQ test are of a very specific nature. "Complete the following number sequence", "Which of these shapes doesn't belong", etc.

A full IQ test has more kinds of problems than that, some of them more open ended and with multiple possible answers. It's still kind of a mess, the tests need to be kept secret to have any value, and the interpretations of what is a valid answer, are sometimes dubious.
