I wish marching band counted as PE here.
With all the required courses for the college path (along with band) she's going to have to take 2 classes over summer school. I've been asking around co-workers and friends and from other parents I've talked to around here it's pretty much the norm I guess. All her friends took summer school this last summer, but DD didn't because we were at
Disneyland 
She'll be taking PE next summer, and probably health the summer after that, but that's only 3 weeks. Foreign language isn't an elective at her school, it's required for graduation. Plus all the usual core classes. It's crazy, we looked over all the required courses and it's impossible to do it all without summer school when you're in band ( or really any 4 year elective).
I remember when I was in high school I had band plus other electives and still only had to go half time my senior year to meet graduation requirements. Sigh.
