As far as I know, UCLA is probably reviewing applications these days. You could try contacting research groups that you're interested in and it might help.
I my opinion, GPA and GRE scores are not important for most graduate programs. What they care about the most is your research since you're supposed to work for a research group after being admitted. So you should try to demonstrate your research ability and convince them that your research ability is better than other applicants in your application.
Good luck!
