What's it specifically called? If there is no pre-requisite that you haven't taken then you're as "qualified" to take it as anyone else who has met any designated requirement.
Actually, I find that people in college tend to be more open-minded and overall nicer, since college isn't clique-y like middle and high school. Unless it's some small private liberal arts college or something, but I think you don't have to worry about that.
I'm gonna go shop for notebooks and stuff to pack for lunch. Yay, first day of classes tomorrow. I'm not so nervous because I already know two of my professors; one I worked with in lab for a year, the other I had for class and went to Iceland with. I'm excited four out of my six classes are small (like under 15 people).
Rant: A philosophy professor I want to work with for my senior project seems to not get every other email I sent. I sent four in the past month, and he only replied to the second one (really quickly after I sent it). The third was a response to his email, and the fourth I sent a week later in case he didn't get the previous one. I'll stop by his office tomorrow in my free time.
