Auditioning for Drama Schools

Hello,

I'm going to be applying and auditioning for drama schools this year for 2019 entry; I'm specifically looking at MA Musical Theatre courses at RAM, GSA and Mountview, but I'm quite clueless as to the audition process and I would love to hear from someone who's gone through the process before or is going through it as well; I totally understand the audition requirements as offered by every school on their websites, but I'd like to know as much as possible about how people have been prepared, how hectic they are on the day, does it feel like a cattle call, etc. basically mostly advice.

Love
