My new posts may seem similar to my past original topics I've posted in this forum. But in reality , this particular post is just an extension of the many questions I have on my mind about physics, as I transcend from my undergrad studies to hopefully my postgrad studies. Right now, as I probably stated in past posts, I'm not really struggling with physics as I am with some of the math courses I took during the past couple of semesters(only the proof based ones i.e, introduction to proofs, abstract algebra), but my grades are not looking outstanding right now, but I really trying to improve my grades with time. My anxiety level arises a little , when I earn average grades on my tests and some of my quizzes because I picture the professor saying 'she shouldn't be taken these courses' or 'she shouldn't be a physics major' as he/she is grading my assignments. I really love physics and I like math too but not as much as physics because I guess in one context physics seems more practical to mee than math, but on the other hand , I like to attempt to solve puzzles that do not have anything to do with the physical world. Again I would like to know if there is anyone who earned there masters and/or pHd who initially struggled and struggled with earning good grades in physics throughout their undergrad studies , but developed better study skills through time? Also are there any professors who have students who earned not so outstanding grades and the professors think internally that the students should not be physics majors, even if the student is seeking help from the professor on homework on a daily basis?
