It makes us concerned but if it is your only choice then you should take chances. At the end of the day, I want to become DDS and I also know there are some other folks who are not even accepted to any school yet!
I am accepted to USC and NYU. I was actually comparing USC and NYU cost...USC tuition is 72,000 75,000 78,000 53,000 and NYU 62,000 per year. Cost of living for USC is estimated as ~26,000 and NYU ~31,000. Still NYU is cheaper than USC and obviously NYU is lecture base which is preferred for many students.
I think first we need to make sure there is no interview or acceptance coming-up and then finalize our decision.
