I took a class this pass semester that grade based only on three tests we took. My grades were 82,74, and 89. Which means I got an 81, or a B. It's showing up on the website where you get your grades as a C-. There's no way that's possible. I never even got a C- on a test! I emailed the professor, but I hope this fixed in a timely manner. I don't know if the professor messed up or if it was the system.
