Juliet has a lot of really great monologues. There is one (sorry, i haven't got a link!) where she's waiting for the Nurse to return home with news about Romeo. There is a lot pacing and being impatient, so there is alot you could do with blocking that would impress them!
I too am getting ready for that whole college audition thing. I feel your pain, sistah!
"This is what I trained to do, and this is what I love about theater. What I love about being an actress is being able to really look into myself and understand another human being. And out my own self, to shape and form and fashion a real human being--and to present that in such a way that people see something of themselves or their own understanding in that human being."
