Emailed the professor and set up a meeting, he sent me a problem by problem result for my questions (ie 17/20 points on 1...) and I emailed him back explaining where I was concerned that I lost points. When I went in to meet with him he had already raised my final grade after looking over my answers and then what I said in the emailed, got the semester grade raised to a B+! Ended up with 3 A's, 2 A-'s and a B+ for the semester.
Since I just transferred schools, this one is much easier for me. I also have the luxury of a GPA reset, so this semester started me off with a 3.75! Now summer classes start Tuesday, and I'm really gonna have to bust ass in them...
