I'm in the same boat. Someone please help me also.
What I just said, disregard that. I'm all fixed up now. Nadia, all you have to do is PM the Professor. That worked for me. :D
Nadia,
It seems by accident that you registered for my class HPBA 2 which does not take first-years. You need to pm or email Prof Nina Atlas. Let her that you accidently signed up for my class. If she has room to take you she'll add you to her list.
