I just got out of my modern physics final exam and am pretty positive I completely bombed it. This will at least give me a C, or even worse a D in the course. Of course I don't know what I got on the exam, but I know it wasn't passing. I am very disappointed in myself at the moment, but I will try to explain. For some reason my brain completely messes up when I'm taking tests. I don't feel as if my test grades are necessarily a reflection of what I know, because just yesterday I was explaining concepts to people related to the test, and when they showed up again I just messed everything up. Everything went wrong. I messed up on simple calc 1 math techniques to solve problems, I misread problems, and I even just realized that the momentum in the zero momentum frame...is just that, zero. I feel like I am the perfect example of someone who makes all the stupid mistakes that you never would normally. I don't think I can stand to work this hard for mediocre/bad grades anymore. Has anyone dealt with this problem? I don't necessarily feel nervous going into the test, I actually feel really focused and want to really solve some problems. I never have eureka moments like I do when solving homework problems. My mind just isn't in the same place. Its not even a time constraint problem. We had 3 hours and that was definitely enough time to do it.
