I might be getting a C- in my physics class, and this is making me paranoid because I had a 4.0 GPA at my previous university, which I transferred from. Now I will be starting out with a bad GPA at NCSU because of PY 208. I am considering using a grade exclusion and retaking it in the last semester of my undergrad(because it is part of my degree requirements), just so I can keep a good GPA. Is it worth it, any suggestions?
