Sorry, but I can't really give you a definitive answer. However, with NYU's high tuition and class size, I have a feeling many seats will open up due to people choosing different schools. So if you have an interview and/or have been waitlisted, there's still a fair chance to get in. This probably goes for any school, but especially the large/expensive private schools...that's my .02.
I was placed on the waitlist for NYU... and just today they sent me an email requesting my fall grades... I don't know what that really means, however that does mean that they are still looking @ waitlistees! Hope that helps
