^^^its not only difficult its impossible, without looking at the other applicants we cant make any attempt at guessing accurately. At the end of the day whats the point to that stat for you? if i say 25% will you be sad? what if I say 85%? If you made me give you number id say less than 20%, that GMAT is a killer for NYU.
If you want consulting fin NY from g-town, thats going to be tough, NYU crushes G-town in that regard.
At G-town all but the top 3 firms (MBB) recruit on campus, however people graduating this year have all secured job in big MC. Its self sourced and not by any means easy. That said, those people are ending up in and around the DC area. There are other schools that will give you a leg up on consulting in NY (not MBB).
G-town is a great school, but it kinda just flys in out of nowhere. It is not a good fit for your goals.
