I took the GRE back in October 2017, and I just found out (March 2018) that I got into UCLA's film school for a MA in cinema and media studies. This thread was super helpful, but also anxiety producing as well. I graduated with my BA in May, and basically started studying all the way until October. I didn't start working until December, so studying all day really burnt me out. I studied my ass off and my scores did improve overtime, but not by that much to be honest. And my actual score was lower than my power prep score, which is pretty unusual from what I've read on here. (But i didn't sleep well the night before so that probably had something to do with it).
I got a 314. 162 V, 152 Math, and 5.5 Writing. I used magoosh + manhattan prep.
I just wanted to come on here and say, and I know it's easier said than done, but don't stress too much about this test. I definitely studied way too much, was miserable those 4 months, and thought I didn't do well enough b.c most of what I read was saying you needed at least a 320 for UCLA, regardless of what the program was....clearly that wasn't true.
My advice would be to study, but don't exceed a few hours a day. Remember they're looking at your entire profile which means writing sample, GPA, rec letters, personal statement, resume, and more. So the GRE most likely isn't going to make or break your application.
