I know many schools just say you have to maintain a good standing, but since you aren't going to finish your graduate degree anyway, then I think you are in the clear. In order to maintain a good standing all you have to do is pass and graduate, but like I said it looks like you don't have to worry about all of that but I would at LEAST try to end with a C. I know last semester I had a C and one of the medical schools I was accepted to said you have to report anything less than a B to the admissions office if it happens AFTER your interview date, so I did and they got back to me and said it was fine but if I had another grade < B then they would have to send my application back to the committee for another review. All in all it turned out okay, but I actually declined the acceptance in the end so it was a waste on my part. You should be okay!
