If you havent looked at creativesocialworker.tumblr.com yet, it was realllyyy helpful to me. The women who runs it was a UCLA MSW and has answered soo many questions for me and will send you a ton of ebooks if you email her (even ones for class like the DSM). Her email is uclasocialworker@gmail.com. For those of you trying again next year she will read your personal statement and give you a lot of great feedback.
Also, I hear that the deadline USC states doesnt really mean anything. They apparently continue contacting people to enroll for months after and even send them info about financial packages.
