well, einstien was a high-school dropout....
intelligence and social aptitude arn't really affected by grades and such... what high school, college, etc gives you are skills, to get yourself a job - whether you're happy in the job or having all your hopes and dreams thrown into a dark pit of dispair is a moot point:p even the most intelligent people on earth can be out done by people who don't know everything....
there's a saying.."the first step to wisdom is admitting that you don't know everything"
there's a difference between a intelligent person and a 'smart' person...
and intelligent person may have all the highest grades in all the subjects they apply themselves to and yet they don't really know how to apply thier skills to a high degree(like styrke said, it's not rare to see BAs and Masters picking through garbage) it's more likely they'll probably end up working at mcdonald's for the rest of eternity paying off thier student loans:p
smart people... know how to use thier skills and apply them in real life....
an intelligent (A - grade student) person once picked a fight with me a long time ago.... and let's just say that wasn't the smart thing to do:devil:
even the most intelligent people are capable of the most aborrant stupidity.... they're only human after all..but some of them see themselves above the rest of us and that's thier stupidity...

it's all a fine line... i'm sure that this will get numerous holes poked through it.
i'm not afraid to admit when i'm wrong or that i don't know everything.....
