Yea, the new science building opened up my 2nd year there, its really nice. However, I was a finance major and was in the loop most of the time.
As for the quarter system, it goes like this.
1st Quarter: Sept 6ish - Thanksgiving
Winter Break - Thanksgiving - New years (really long break)
2nd Quarter: New Years - Spring Break
3rd Quarter: Spring Break - June 13th ish
It goes by really fast considering each quarter is only 10 weeks. Before you know it, it will be time for midterms. Seriously, like 3 weeks into the course, you will start talking about them. Then, finals are just around the corner after that.
However, have you thought about Loyola University? It's a much better med school.
I was considering it, but I did not have enough from financial aide to help me go through.
