Online IQ tests are very very very very basic. They're not accurate enough to tell a true IQ only to give you a range inwhich to expect. I had to take one last year during my Sophomore year at Tri-State University when I was studying Mechanical Engineering. It was part of a University study to test the intelligence of the average student in each of the Universities offered majors. I scored a certified 149. Where as on numerous online IQ tests I've scored as high as 175. There's a big difference between sitting in a room by yourself with nothing but a pencil and a piece of paper and sitting at your desk where you have access to a calculator and other resources. If anyone has the chance to take a real IQ test I suggest it. It's quite interesting. One of my professors tried to get me to take the test for MENSA. I still don't know if he was joking or not...
