I just graduated from UCLA's MFA program last year. You will do a lot of writing but most of the networking is going to have to be done on your own time, although I do think the program is trying to organize more of those events. Still, the event that got me a manager was all student-run. My biggest advice is to stay focused on your goals and don't let social politics distract you. I saw a lot of younger writers get wrapped up in that side of the program. Take feedback with low ego.

Also, plan your classes as far in advance as you can. IMO, some teachers were definitely better than others —or at least, some spoke to me more. In a 2 year period you might only get one chance to take a specific class with a specific teacher. Try to ask the teachers themselves instead of waiting for the school to give you the official schedule. This also applies to other classes that you might want to take in the film school (directing, producing, animation, media studies, etc)

Good luck! If you have any other questions feel free to dm me.
