Agreed. They're useless, and I can exercise completely fine on my own. It's the biggest waste of time, ever.The only thing I would do is abolish compulsory PE classes. Those are the worst things ever to have been invented for high school.
Another thing would be to change the vending machines so they don't have a timer on them, and change the selection instead of all the diet crap that tastes like medicine.
Also, I'd change the class/subject policy. I wanted to take summer courses to get ahead, but at the last minute I was denied because if I failed a course, then my schedule would be too messed up. Or the counselors were too lazy to bother with it.
