So, I am struggling with one of my upper division math class(Partial differential equations). I contacted a close family friend to see if he can help me or if he knows anybody that can tutor me because he is a math professor at a college. Long story short, a grad student emailed me and said he is willing to help me because he had the same professor with same class, but has not done that class for a while but is willing to catch on after reading the notes.
Then, he asked to email him the course topics and I emailed it to him. Two days later no respond. I am frustrated because I am really having a hard time in that class and recently failed a quiz, and I am stuck on the next homework assigned and have another quiz this week. I don't want to go to my professor for help because he will ask why I did bad on the quiz, which I feel embarrassed and I had been going to his office hours for help before quizzes and homework. So, what do you do in this position?
