what are the real sorority rankings here?

Greek life is not super huge here, I think about 20% of students are involved in it. There are a bunch of great girls who are not in a sorority here, but who are friends with the sorority girls.

Top: KKG, Ivy Society, St. Anthony Hall (number one at Trin, accepts both girls and guys)
all of these girls are mostly intelligent, have great parties, and generally are very pretty.. definitely at least solid 8s and above.

Middle: none (we don't have many sororities here)

Bottom: something with Zeta in it... I'm sure they are nice girls, (I personally don't know any of them, most of the campus doesn't know them either) but if you're not on the women's rugby team, you probably won't be interested. They aren't on the social scene at all, but for some people that's what they want!
