these tests are kind of bull... they are made so that people get high scores and then pay to get the results sent to them acknowledging them how intelligent they are. the proof is that im a complete dumbass and i got 157.
my dad made me take one in argentinas society for gifted children when i was like 12 or 13 (why all parents think their boys are more intelligent than others?). i did quite good and could actually qualify to enter but it wasnt so out of the ordinary. my younger brother lucas was almost off the charts, though. he is the only person i know that has tought himself how to program in all major languages. and he did it in less than 3 months... on a whim.
