If I have an advisor, I don't know who it is. They just have a general "advising day" in our department once a semester, and it's such a small department that when you have a problem you can pretty much go to anyone with it.

I did send an email to the teacher of the class I need letting her know what happened, and telling her that if I can't get the class this semester that I need to put everything on hold until next fall when I can get it. I just got a reply from her saying to just come to the first class and she'd see what she can do. Unfortunately I've never seen the school let anyone into a class that is full. They say they can't because it affects their funding.
