How selective are the sororities?

<p>Does anyone know how selective they are? Did a lot of girls not get bids?
(I've heard varied things…)
Also if anyone knows anything about rushing as an upperclassman that'd be helpful :) I'll be a third year (almost rushed this year, regretting not doing it), which I know is unusual but happens, but it would help if I knew the likelihood of getting a bid
(I definitely consider myself a sociable person and everything I'm just hoping being a third year doesn't keep me from getting one!)
Thx guysss</p>
