incoming junior transfer student trying to join sr

Hi! I am an incoming junior transfer student from a California community college and I have always wanted to join a sorority ever since I was a little girl. Can anyone give me their advice on if I have a chance to get a bid from a sorority if I'm a junior? I was hoping so because UCLA is a junior-level only transfer school but I also know at other schools some of the first girls they drop are juniors unless you're drop dead gorgeous-- so I'm worried. If anyone can leave me some (nice) advice or their opinion that would be greatly appreciated!!
