Seems like immaturity (especially the Groucho Marx attitude).
Unfortunately, immaturity is rife in teenagers; especially teenage boys.
He’s probably at the age where he doesn’t want to listen to you either.
Is there another adult he respects who can give him the message: “hey, where you spend the next 4 years is a serious decision; and do you really have so little self-respect that you think less of schools that want you?”
