Nope! Just show up. The class runs about 3 hours as it is a real Basic Avy awareness class. It's not like those presentations where they try to get you to sign up for a paid course through their guide company.
Yeah, FOBP is definitely the best free course you're gonna find. I went to one at REI and it was basically just a 45 minute infomercial for Colorado Mountain School. The only possible good it did was potentially scare some idiots from dropping in at Loveland Pass. Which I guess shouldn't be discounted. No real info shared though.
