Rush week at WSU

[lcrews5]

Hi everyone! I'm going to be a freshman this fall at Washington State University and just registered for Rush week. I'm new to the Greek world and am in need of some advice/info!
First of all, does anyone know if WSU is considered competitive when it comes to greek life (hard to get into)?
Also i've read that letters of a recommendations are a good idea, would it help if I had my Aunt write a letter of rec for me? She was in Alpha Phi which makes me a legacy to that chapter. Or would it not really make that much of a difference?
I really would like to talk to someone who knows especially about the greek life at wsu, i've heard most girls join a sorority after rush but i'm still nervous!
