NYU chances

I have a 3.4 and 30 act 1380 sat.

You haven’t given enough information for us to determine whether or not you would qualify for admission. Even with enough information, it’s hard to tell. The only people who can determine whether or not you’re admitted into the school is the NYU adcom. Seeing that the NYU GPA average is 3.7, their SAT average is a 1400, and ACT a 30, I’d say that you’re on the low-end of admissions. You have a chance, but know that you’re chance, especially with that GPA, is going to be far lower than the applicants you’re competing against. Anyways, I wish you the best of luck in the admissions process.
