I agree with what Desi has posted.
For those who were asked to retake the DAT (or were specifically told that a higher DAT would help their admissions into NYU), what other schools have you heard from? Is NYU your top choice?
How you play the game from here is going to depend on your answer to those two questions. I'm assuming that you have not been accepted to any other schools, OR that NYU is your top choice.
I would wait until after the Jan 16 date before committing to anything. NYU might send out a slew of acceptances then, and yours might be one of them.
With NYU, you always need to keep in mind that admissions just isn't nearly as competitive as it is with other schools. That does not mean it isn't a good school, but it does mean some other things. In any event, know that NYU has to send out *many* acceptances to fill the class, and that you might be one of those, no matter what you've been told already.
If NYU is your top choice, and you simply must attend there, then do this: call the admissions director and the dean, each individually. Explain why you want to attend NYU, and explain what you will contribute to the program both as a student and an alumni. Let each of them know that if you receive an acceptance to the school, you will forward the required deposit right away (overnighting it if necessary).
I can tell you that this works nearly 75% of the time, and letting the admin. peeps know that you WILL attend the school if you receive an acceptance (and that you WILL send $$$ right away) is usually enough to have them take a file that is sitting on the fence and push it to the admitted pile. Only do this if you are serious about the school and wish to commit. Doing this without true intent of matriculating ruins the process for others.
Good luck!
