I think everyone on the previous forum was following IQ tests on different websites. It would be way better if all of us can attempt the same test as it can produce better conclusive analysis. I have heard from many about the website:
Its better than most of the phony tests available online.(And no I don't have any share in the site's profits!)
They send a detailed report on payment of a certain amount of fee but you can know your IQ score for absolutely free.
KEYNOTE: There is only one set of questions which will be repeated every time you attempt the test. So, do it when you know that you have the time and space to complete the test. Hardly, takes ten minutes or so.
ALL THE BEST!
