That is stupid. In my experience though High Schools have STUPID rules sometimes that there isn't much you can do about. I'm curious how much PE is required ? In CA we only have to take 2 years of PE, one of them freshman year. Do they specifically have a PE for sophomores that must be taken? Is Drivers Ed a required class for High School graduation?
What I would do is to start and talk with the PE teacher. If you don't get anywhere with that then talk with the principal or vice principal.
Good Luck.
