I took an actual IQ test administered by a psychologist and all that jazz, and earned a result of 145. My brother did the same and tested at 160, and is an idiot who leeches off of other people and wouldn't know a (academic or otherwise) work ethic if it kicked him in the nuts.
Results of that test do not take into account what one will choose to do with their inherent abilities.
Of course, then you have that wonderful ego boost when everyone in your class asks you, "What did you get??? What did you get???" And you tell them, and they're like, "That's it?!" It's like FUCK!!!!!!!!!!!!!!! STFU.
