If she was making good enough grades to be admitted into college and onto the cheerleading squad and now she's failing classes, to me that's slipping. We are far enough into the school year to make that determination.
Maybe that's why she's yelling discrimination, it's the only way she can win her place on the cheerleading squad since she can't make on her grades.
She needs to study more, obviously, I just think "if she was using her brain instead of her body, her grades wouldn't be slipping." was a little rough.
She's just a kid, I don't want to rake her over the coals for wearing a tank top at a part time job.
