I haven't done any free classes but I was an undergrad at the University of Utah and took an online creative writing class my senior year. It was a decent class, but not the same class as if offered now for free, apparently. Mine had fewer assignments and no poetry assignments...
IMO I've never felt like I got nearly as much out of writing classes as I have out of simply writing and exchanging critiques with peers.
