According to Nerd Tests, I am a "Cool High Nerd."
Kinda weird results there; I went to Caltech (and aced all of the math or logic-based sections of the SAT and GRE) but scored below average on Math/Science nerd-dom. Maybe I'm good, but just not nerdy about it. I'm also seriously not into sci-fi at all, though I have a large comic collection. I should also add that despite my low tech/computer score, I have actually used FORTRAN. I found this test via Vic's site.
UPDATE: Somehow this test has my little sister being more than three times as "dorky/awkward" as I am... this is patently untrue. I question this test's validity.
