Quoting the UC Davis Greek Life website:
"Send a request to the
Greek Life Office to join the GoGreek email list. You'll receive weekly updates about all of the upcoming Greek events you're welcome to attend to get an idea of what it's like to be Greek at UCD. Go to as many of them as possible or go to just the ones hosted by groups that interest you.

There are 10 sororities (9 NPC & 1 non-NPC) on campus, so while some California schools are laid back on Recruitment, a RIF could be a nice introduction to each chapter that the women, who don't try to find RIF's, would not get.
Best bet it to contact UC Davis Greek Life.

They should be able to answer your questions.
