I’m planning on being a musical theatre major, but I’m not 100% set on my audition choices. Would it be unwise for me to apply to the actual school so soon before (maybe a month or two) before I actually send in a video/schedule an audition?
Most schools will not allow you to set up an audition/audition without having applied. There are a few that ask that you wait till after you pass their prescreen before applying. You will need to check with each individual school regarding their process.
