what are the real sorority rankings here?

Tiers are more about how the outside sees an organization. If thats how you want to look at it then Tri Sigma is running the show this semester after a stunning resurrection from previous semesters. They got the most girls by far all are pretty, classy and have standards. They are very approachable. Now thats not to say anything nasty about the other organizations. AOPi is up and coming again and AST is pretty popular with the Fraternities, though Lambda just seems to get worse. They used to me cool but the past few pc's are getting just not good to say the least. and thats not the world opinion, its just mine. Hope that helps
