Junior rush question

Hi so I recently transferred last spring and I’m hesitant about going through recruitment this fall. I hear mixed things about rushing as a junior and know it’s not preferred. It’s always something I’ve wanted to do but never really had the opportunity. Do sororities take juniors or is there an upperclassmen quota like there is at some schools? If they do, is there any tips anyone in a sorority can give me for juniors going through rush? Thxxx
