More free IQ tests

Here are several more free IQ tests available online. Again I'll post the number of questions and approximate time given for completion. Apart from the BBC's Test the Nation these are all very short, free IQ tests.

A.C.E Intelligence test

A unique and interesting intelligence test with a strange final question, the purpose of which I have no idea. This test also has a section where you can specify if you already know the answer to a question, or whether you're just making a guess. It has a professional feel but the other aspects of the A.C.E. society and website seem dubious to say the least (check out their about us page!)

Time: 20 minutes
Questions: 33



Simple IQ

Pretty quick IQ test which is age related and time limited. It doesn't mention how the IQ is calculated or calibrated, but the bad jokes make up for it.

Time: Max 13 minutes
Questions: 38



IQ Test.com

This is similar to SimpleIQ (above) and the questions are almost identical (so someone has been stealing from someone!) but seems to be a lot more professional and contains more information. It also e-mails your results instead of displaying them.

Time: Max 13 minutes
Questions: 38



BBC's Test the nation

This televised intelligence test was very popular, claiming several million viewers. It's also very accurate and has been developed using several hundred people. The free IQ tests above simply don't compare in accuracy. Unfortunately, this test requires a broadband connection (due to videos) and as such isn't suitable for everyone.

Time: 45 minutes
Questions: 170



IQ test for free

For bonus points you might want to try this one, which differs from the rest of the free IQ tests in that it's VERY accurate in it's answer and only has 9 questions!

Time: < 5 minutes
Questions: 9



These free IQ tests are less accurate (with the exception of the BBC test and the final one) and are grouped because they're pretty quick to complete. If you'd like to get a more accurate gauge of your intelligence then feel free to look at the earlier post Free IQ Tests
