i have taken a few mensa tests online, in school and actually as a form to get in... i'm only 15 and i'm not 100% on whether they allow 15 year olds, or if there is a section for younger participants... but it's just logic after all on most of the questions and the tests and what not, i know i did "superb" as so eloquently put by my english teacher... <_< but i will try and find out exactly what my I.Q is...
