Elizabeth says in reply to both:
I also believe that Harry will somehow ace that Potions OWL and, in
turn, "force" Snape into accepting him into the NEWT Potions.  McGonagall, as 
head of house, would be in the position to actually do the "forcing" as Harry would have no leverage against Snape as "merely a student."  I would imagine that even despite considerable "bad blood" between Harry and Snape, or with any other teacher and student, there would be very little the teacher could do to "reject" any student who was qualified to take their course, especially since it will be part of his requirements for Aurour training.  Snape's argument that "his dad teased me when we were young and then he went and spied on my private shame in the Pensieve" would have little weight with Dumbledore as well.

Angel comments:
Actually, that last section would have quite a lot of force. Snape can
argue to DD that Harry can't be trusted with Occlumency, and is in fact
downright dangerous, meddling in things that don't concern him.
I rather think there's some horsetrading between the heads of houses
over who does which subject and with whom.
