Here are a couple of threads to skim over for you to get an idea of how recs work and how you can attain them. There are a bunch of related threads when you search under "recommendations."
Which school are you going to go through recruitment at? Maybe someone at that school will be able to tell you how the sororities there work. Every school is different.
For example, at UF recommendations are nice but not necessary. I went in without a rec and things were fine, but maybe at the school you'll be rushing at, they would prefer a recommendation...
And don't worry. Rush will be okay. Please keep us updated! Most of us are as excited about recruitment as the potential new members are!
