TOD
In high school, it was any foreign language. I took one year of Latin, two of Spanish, two of French, and a speeded up version of German that covered two years in one.
In college, my degree program was screwed up somewhat, so I remember taking a history of jazz class as my only elective. Everything else counted to the degree. What might have been electives ended up being two classes I found out at the last minute I needed to graduate, a science class with a lab (geology) and world geography.
No electives in the master’s program, but I did get to create a lot of classes, like black musicals in the 1920s and Nervous breakdowns in Stephen Sondheim musicals.
