Ever since my first midterm, I've been studying hard with a friend and drilling through very difficult problems almost everyday and throughout the weekends. I think this time, I did much worse. Admittedly, there was one or two chapters I was weak in, but I thought I felt well prepared for the exam, and yet I still did terrible. I put in half the work for linear algebra and calculus, and I'm doing better in those two classes. Is physics just not for me? Should I just stick with math instead? I did enjoy spending my free time doing practice problems on the weekends, but it is quite discouraging and depressing when you try so hard and yet do terrible on the exams.
