how the hell does one find out about practice groups? i opted not to take a class this session for need of saving money for other things and know practice groups can be relatively cheaper than official UCB classes (not that UCB classes aren't worth it, this just seems a suitable replacement financially until i can afford classes again), but i'm terrible at schmoozing and all the stuff that comes with finding out top secret information like this. so again, how the hell does one find out about practice groups?
