Why do you think you have no chance being ranked at 11?
Yeah, I got a call today this afternoon (I left a message this morning) and I'm now 100% going to NYU. Jill said they placed 45 people on the waitlist, which is considerably larger than previous years. As Yeti81 stated, they have in the past taken 5-10 people off the waitlist so if you're in the top 10, who knows what will happen between now and day 1 of classes. If you're where I'm at, you'll go with plan B.
