This poster just joined today. This is obviously a joke.
Our high school does not allow you to register for an AP Exam unless you are in the class.
Just find an even less reputable school, but really shoot for the bottom of the barrel this time so he doesn’t have to keep switching schools. You might want to do the same for college. 
I vote not real.
I doubt a parent would refer to a school as “less reputable.” Less competitive, maybe. Less reputable? I think not.
There’s a relevant Simpsons line here, “why try to compete with someone who’s just going to kick your butt anyway?”
MODERATOR’S NOTE:
I have no idea if this is real or not, but since the OP has not returned to answer the questions posed, I see no reason to keep this open. Closing.
