epends how you say it. If it is learning potential than I am considerably above average, cause I go to a private (smarter than most state schools) school, and am among the best in my year at 'picking things up'. As far as the whole, 'well you can't be that smart if you did this (insert activity here)' (basically common sense), then I have it, but I put it in a locked safe inside a barrel which i locked in a bigger safe, dropped into the deepest part of the ocean and then took the entire part of the ocean (safe-barrel-safe included) and put it in the back of my sock draw.
As for street smarts, I tend to be pretty observant and could probably pick up a societal behaviour pattern relatively fast but once again ... sock drawer-ocean-safe-barrel-safe.
Summary: I put Considerably above average, cause I don't count the lack of will to use intelligence a dumb move, just a lazy one.
