This test measures IQ with an overall score as well as scores for component abilities.

The Intelligence Quotient (IQ) is the measure of human cogntive ability. Scores are set so that the average is 100. There is controversey about how IQ scores should be broken down, this test uses the 3 domains from Hampshire, Highfield, Parkin and Owen (2012) of (1) Short-Term Memory, (2) Reasoning, and (3) Verbal. This model seems to fit best on internet populations.

This test has six sections. Each section has its own instructions. This test is meant to be taken solo, without references or materials. It will only be valid the first time you take it, so if you want an accurate result do not start the test until you are ready. The average person takes between 10 and 15 minutes to finish the test, and this is important. See the graph below:

There is not much benefit to taking a super long time on the test, but if you speed through in less than 10 minutes your scores will be much lower than they would otherwise be.
