Too short, too simple
First, this is definitely too short. One question with several unequally weighted answers is not enough to determine nerdom. Secondly, you should differentiate between a "nerd" and a "geek". The way I see it, and what I tell most people, is that nerds have academic knowledge (science, programming, math, history, something that is taught), while geeks have trivial or media knowledge (Star Wars, Star Trek, anime, movies, TV, something that is not taught). There are cross-overs as well, such as music, which might go either way.
And, yes, I realize that my review proves that I am a nerd.
