Many different intelligence tests are available online. Here is a list of a few you can try. Do not pay for any results. If money is asked for go to a different site. This assignment does not require any payments of any kind. There are plenty of sites that will give you free results.

Give one a try and then do a web search for intelligence tests and see if you get the same results when you take a different test. Do the websites tell you how reliable the tests are? Do they provide information on standardization or validity? If your scores on the two tests are very different, what might account for this difference? Tell me what additional free intelligence test sites you found and if you agreed with the results.
