They should give you the pre material prior to class- it'll have access to some stuff like flows and callouts. Bu honestly you'll have time. It's not that busy. Just partner up with people and work over systems and flows once you start class. They'll get you through it. It's not bad.
Hey - at least you guys get per diem lol. That was a recent addition a few years back.
