I was watching a T.V show and it talked about I.Q, so I decided to look up online who has the highest I.Q score, so I found this website that was about I.Q's, it was started by a guy who basically had the same question I did but couldn't find the info all in one spot, so he created this website, The highest was Physicist / Engineer Kim Ung-yong who scored 210, one of the more unusual things was the number 2 guy, Bouncer Christopher Michael Langan with a score of 195, the guy has an I.Q of 195 and he's been working as a bouncer in a bar the last 20 years.
Towards the bottom of the page it has a good I.Q test to take, one of the better ones I've seen, it's based on spatial acuity, there's 40 questions & you get 40 min, they start off easy, but they do get harder, much harder, if you don't know an answer don't guess as it will penalize you for guessing, just move on to the next question. it will give you your score at the end, at the top of the website it has a I.Q traditional ranking, so you can see where you fall after getting your score. I got a score of 112, the ranking says that 90 - 109 is average, so I'm just above that. I was able to get about 30 of the 40 solved, left about 10 blank. So try it out and post your score, remember it takes 40min though.
