We have a BUNCH of electives. We also have more class periods in the day (9) so students have more opportunities. If I remember correctly, we have:
-Intro to Theater (6th)
-UIL (a class literally to "practice" Academic UIL events, and free time when that's over)
The (Required) classes are considered electives, but have to be taken at some point while students go through MS. There's also a lot of pressure for students to enroll in Academic UIL events on our campus, so the UIL classes are very popular.
I think we have too many electives, personally, but because of the # of class periods we have it tends to work out okay. I would also say that easily over half of our 7th/8th student body are involved in an athletics class.
