*scratches his head*
I dunno. I've taken some aptitude tests in middle and high school and I was rated well. One of the aptitude tests I took had over 20,000 schools participating all over the country and I finished in the top 5%.
However, if you look at my grades, you'll never figure THAT out. For all the brains I supposedly have, my grades in school are at best average of slightly below. I do better at lab than I do in class or at theory. I don't know why. I was (and still am) not so good at grasping concepts but I somehow seem to excel in finding applications for 'em.
Yes, I know. I'm weird
