I have had a professional IQ evaluation in the past, and the GIQ I obtained from this test is exactly the same as I obtained from my professional evaluation, so it is apparently pretty accurate. It asks for information at the end of the test, I just put fake shit, they ask for your E-mail address but then it takes you to results without needing to answer any messages. You can take the test via Tor, and definitely should imo. It does require javascript though, yuuck. www.funeducation.com/Tests/IQTest/TakeTest.aspx
