Alright so I'm a sophomore student right now. I'm enrolled in what I feel like is a hard Astrophysics class. Myself having only taken calculus based physics I&II. I just made an 80 and a 50 on my homeworks. I don't know why I'm struggling so much. I was really good in physics I&II. I want to do research with professor and I'm really passionate about physics. Should I go talk to him? If so, what should I say?
