There is still a good chance, if you are a competitive aplicant. Don't forget that schools interview up until March, and it's only January. Though there are some schools, like UOP that have small clesses that tend to fill up quick. But NYU has the largest class, and some of the poeple that got in without interview have deadline for deposit, and some will not pay.
Don't worry, try to stay involved, if you have more grades out, send it to the schools with a letter explaining your accomplishments or if you have new research/volunteer/shadowing.
Good luck
Just so you know UOP has one of the larger class sizes which is around 140.
NYU definately has a larger size like u said.
