PE question

Got a question about practices in girl's PE principaly high school.

Way back when I was in school, boys PE had bars of pretty generic soap in the little metal trays by the shower heads. And the guys all used it.

I'm wondering if girls use school supplied generic soap, or bring stuff of their own.

I figure Morgan doesn't know either and I'm wondering what Chris or one of the other girls might suggest if he complains about the soap.
