Just to add to the to everyone saying i.q tests are bs... they are...
the bbc did a national thingy a while back, i got 120 on that, did a random internet one and got 103 and i actually did the mensa one and got 155.
Really the only way to say if you are smart or stupid is, have you ever responded to a spam e-mail and given some random internets people your money? if so, you're a dumbass. If not, you're not a dumbass. And when it comes down to it, thats really the only two levels of intelligence that matter.
