So, I am an undergraduate student taking partial differential equations. This class can be so stressful at times because I do not understand the lecture material, and thus it makes it hard to do homework. Moreover, we have a quiz every Friday based on the homework, and homework is due on Friday.
So far, we are going over 1D wave equations and I do not understand any of the lecture material at all. Moreover, If I do not understand the lecture material I can't do the homework that is due on Friday. Other students in that class are lost too. It just doesn't make sense that this course is required for undergraduate level in order to graduate.
What do I tell my professor in his office hours if I do not understand the homework at all? I am nervous because I do not know how he will react, and I did not put any solution down because I am clueless. How would you react if you were a professor and I went on Wednesdays to your office hours and homework and quiz is due on Friday?
