I am a junior in physics. Things have been going pretty good (not flawlessly super) so far, with the exception of one class: upper level mechanics. I just cannot perform at a sufficient level and I don't know why. We just took a midterm a few weeks ago, one which I studied pretty hard for (started four days early and forsook some of my other work for the week); I studied the example problems, end of chapter-problems, and I fully utilized my professor's office hours for questions/help. However, I did horrible on the exam and the assignments are not going well either. I also know alot of other people are struggling, but still this does not help me out. Is it possible I'm just no good at physics? I considered this, but then that would not explain how I'm doing fine in my other courses. Perhaps just alot of mental pressure and over-hyped fear of the class? I really don't know. I really like physics and would like to pursue grad school. I just don't know how to conquer this class though. Any advice? Thanks.
