What is your major?
They have a ranking system of majors and will fill he class with Theater majors first, then Stage Management, and so on. My major was electronic media - I feel into the third tier and never made it in. It's a very popular class, so if you do not have the correct major, it's hard to get into.
As for the class - it revolves around the Creative Entertainment Production Life Cycle. What are all the steps involved with the concept, creative development, production, mounting, opening, operation, and sustainment. My understanding is that they focus on each step for a week.
