honest rankings, imo

You shouldn't judge a sorority completely based off what "tier" they are, but if you are wondering (because a lot of girls do and we can't even deny that) here is how Greek life is set up here at UCM.
Top tier: ASA/Tri Sigma (Interchanges a lot, very social and competitive)
Middle tier: Aphi, Aopi (although polar opposites in personality)
Lower mid: SigKap, Delta Zeta (more grades oriented, less social)
Bottom: AGD (very unique girls & diverse)

GPhi is too early to really tell; personally I would rank them lower mid but no one is very familiar with them as a whole yet.
