I do have to ask what the hell is wrong with someone that they're failing P.E.?! Pretty much every P.E. class that I've had, as long as you're dressed out  and do something when they turned you loose into the field, you were basically guaranteed an A.  First and foremost, I do feel bad for you for being responsible for her, my only concern here would be that sooner or later, the parents will blame you for their precious piglet failing. Perhaps if you were one of those parents that made their kids 'earn' the WiFi password or w.e every day...?
