I'm sure there were some courses with an easy rep, but I didn't know about them. Easiest I took was American History, but again, because I'd had a more thorough version earlier. I mean, I took art history (the one I blew off) as an easy course, and had to write several papers that were actual work.
The physics department taught what was informally known as "Physics for people who hate it" that was actually a neat class. It was very hands-on and real world scenarios. It was pretty popular. I used to listen in when I was working in the lounge next door. Ocassionally, us majors would get roped into helping out. Usually holding some contraption in an awkward position and getting mocked.
It was a great department.
