About This Quiz

Think you're a genius? Everyone knows that IQ tests relate to intelligence, but what do those numbers stand for an what do they really mean? IQ actually stands for intelligence quotient, and understanding the difference between having a low and high IQ according to these tests is not complicated at all. IQ is simply a person's reasoning ability, or ability to solve problems. IQ tests are just problem-solving tests. The results of these tests are then compared to the statistical average amongst test takers of the same age. Some people have above average IQs according to these tests and some fall below, but many people will be just about average.

These tests are not about how much you have read or how much knowledge you have obtained over your life, and it is somewhat impossible to study for them. While education largely relies on memorization, even the strongest memorization skills will not have much to do with how a person scores on an IQ test. In fact, they are often given to young children as a tool to help inform their education, before they have had a chance to absorb much of the acquired knowledge adults have. 

If you are ready to put your problem-solving skills to the test, test your IQ with this quiz!
