dan...,
sign up for private voice, through Tisch. It's a 2 hr. course. That'll give you 18 credit hours (no extra cost). Also, go to
www.phtschool.org, click on Curriculum. For the actual schedules, you'll have to look under Students and then each day's schedule (or, of course, you could ask a playwrights student, but they're notoriously busy). Good luck and have fun!
Oh, and thanks, sooz, we cross-posted.
