I'm considering taking mechanics (lagrange/hamilton etc.) my second year coming out of physics II (electromagnetism), but I've heard it's a very difficult course. In fact my advisor advised against me taking it since i have the prerequesites but not the "experience". The problem is the usual next course isn't until the fall, so if i don't take mechanics I'll be behind a sesmester or two. I'm hoping to get some feedback from people who have taken the course on just how hard it really is, or if it's hyped up a little. Is it possible for me to make a B/A coming out of physics II?
