rushing as a junior

[greekcheek]

first of all i'd like to apologize if this has been asked numerous times before...

I was thinking of (fingers crossed) transferring to UCLA as a junior next year. I've always wanted to be in a sorority...will I still have a good chance of getting a bid even if i'm a junior? I heard priority goes to freshmen or sophmores. am i at a disadvantage because im trying to rush as a junior?
