A few people have asked me about this before, and I myself am curious to know too because I have never really taken an actual test like this. So I found quite a good online test and you all can go try if you like. (Ok maybe I didn't really put much effort into finding the website, but with a domain name like iqtest.com and detailed results given to you if you pay, how unreliable can it be?)
