I'm considering enrolling in mechanics (lagrange/hamilton etc.), and I've heard it's a very difficult course. In fact my advisor advised against me taking it since I have the prerequisites but not the "experience". I was hoping to get some feedback from people who have taken the course on just how hard it is or whether it's been hyped up. Do you think it's possible for me to get a B/A coming out of physics II (electromagnetism) if I work hard?
