A waitlist slot isn’t a no so it’s POSITIVE!!! 
@Nancyb656 you’ve got lots of great info here and the problem is it’s hard to organize into anything resembling the matrix everyone wants. I agree with @artandtechmom that having a focused list of schools that are good fits is as or more important than having a big list but it is SO hard to get objective information on where your particular artist is a “fit”.
I don’t know if NYU is on your list but it’s an oddball. They audition over 3,000 and accept probably 500-600 for a Drama class of 350 but MT is only 65 of those. “All Studios” applicants have a better overall chance of admission than “MT only”. At my D’s audition about 70% of the Drama applicants auditioned for MT as their first choice studio.
