Mid-term Angst

On Thursday, I took two midterms. The second was in Matrix and Linear Algebra, and it seemed to have gone well. It was the first one, Calculus III, that has me concerned. Of the ten problems, I only managed to work seven of them. When class ended, about half the class was still in the room. I sent an e-mail to the professor asking about this, but have gotten no reply. I had sent two previous e-mails to this prof, and gotten no response to them, but he seemed to have considered them. I'm wondering if there is to be a curve. If not, I may have hit the first real bump in my return to school. Time will tell.
