That price is just for the program. If you live in an NYU dorm over the summer, you have the option of getting a meal plan, so thats a way to pay for food. If you attend the CAP program, you have to find your own housing and you are not guaranteed housing, so make sure you apply for summer housing as soon as they start accepting applications.
here is a link to the rates for summer housing

It is a competative program to get into, but they mainly look for potential. There seemed to be a pretty even mix of bass/baritone and tenors. There seemed to be a good mix of everything. Level of dance experience, acting, and voice types.
If you have any other questions, message me. I will gladly answer any questions about the program.
