I think a lot depends on the teacher. If there is a really good teacher which challenges their students then any course can be a great learning experience (even beyond the material covered). Obviously, it will always be different between schools. If I were you, I'd ask fellow students to see if anyone has taken a truly interesting/challenging course.

I took a Negotiations course my senior year of college and it was easily my favorite class of all time. There was a lot of roleplaying and class debate, but the teacher played Devil's Advocate and poked holes in everyone's arguments. He truly required us to think creatively and analyze a situation thoroughly before speaking/writing, or else he'd rip us apart. It was a breath of fresh air after many other classes were purely focused on learning concepts, rather than applying them creatively.
