In Calc 3, some of it's not too bad, but other parts were a pain in the ass. Although this might have been because my professor was strange and didn't always follow the order of the book, so figuring out what sections were what and what problems you should be doing was tricky (he didn't actually assign homework in class). Hell, some of the stuff he covered wasn't even in the book. That, combined with his thick accent (seriously, sometimes understanding what he was saying was damn near impossible) made that class more trouble than it should have been.
The one class I'm actually going to miss from this semester is The Military History of the United States 1900-present. It was a crapload of work, but was really interesting. For instance, do you have any idea how many problems around the world today can be traced back to idiotic U.S. and Soviet policies in the 1950s? The class is even more badass because before coming to my university, the professor taught at West Point.
