FSU Marching Chiefs Audition?

Hello. I’m an incoming freshman at Florida State University and I’m super interested in joining the Marching Chiefs. I play clarinet. I heard the audition is very competitive and that the program requires a lot of commitment. What can I expect from the audition? How should I prepare physically? And how much of a commitment is the program? I just want a heads up since I’ve been a bit antsy about the whole thing. Thank you so much!
