Hi: one doesn’t register for Unifieds. It’s a free event. You just go to any of the 3 locations. NYC, Chicago or LA. Some folks book audition there for ones they have been granted. There are a few walk in audition opportunities as well. Mary Anna Dennard has free 5 part video series about Unifieds on her VLOG. Google college audition coach to see video or you tube mary anna Dennard and her college audition videos will pop up for free. Went through this process last year. It’s a maze of crazy. But try looking at the 5 part video series on Unifieds fine by Mary Anna Dennard. Again you don’t register.
This is misleading. While you don’t register for Unifieds, per se, you DO have to apply to and register with each school you want to audition for BEFORE Unifieds so that you are given an audition slot. Otherwise, you’d be relying totally on walk-ins, which many schools do not do, as all their slots are filled.
