Weekly Classes?

I’m taking the L1 in December and was thinking of taking one of the live weekly classes that are advertised on this site and wondering about people’s opinions. I’ve done a search on the site, but haven’t seen any discussion of this in the last couple of years. I’m looking to take classes mostly as a way to keep me on track and focused. I know I tend to do better in a classroom setting than I do when I’m completely self-directed. So any thoughts on classes in general, or specific programs? The NYIF weekly classes seem to be much more expensive than everyone else, and I’m not sure what I’d be getting for that.
