I got two C's but they are weird.

I want to go NYU obviously but I got two C’s in my sophmore year. They were 84’s(a B is an 85) and North Carolina didn’t change their grading scale to the 10 point scale which everyone else uses until next year. Is there anyway I can explain this on my college apps?

Yes, I think you can put this in additional information. I would also talk to your guidance counselor; maybe he/she can also write an explanation if necessary.
