what are the real sorority rankings here?

All of the sororities are awesome and unique. I have only heard minimal complaints from some of them. As for the rankings, it all depends on who you are and what you are trying to get out of a sorority. If it is boys and fun, AXO. If it is fun, boys and sisterhood, KKG. If you are looking for a great group of girls who consistantly win Greek Week, KAO. If you are looking for a diverse group of women who have an awesome charity, TriDelt. If you are looking for a great new group of friends and a ton of bonding and sisterhood, Go ADPi. All of these are great choices. The two most competitive to get into are KKG and AXO with KAO being a close second. TriDelt has a great group of girls along with ADPi as well. Think of what YOU want out of a sorority and which girls you are most like and look up to because thats what really matters.

Definitely agree with the comment above. In regards of how hard the sororities are to get in to it is probably 1) KKG and AXO 2) Theta 3) TriDelt and 4) ADPi but each sorority is truly unique. The Kappas are the party girls with a great sisterhood. Alpha Chi's are known for being the pretty girls that never get in trouble. Thetas are the smart girls with a very close knit sisterhood. TriDelt is a diverse group of ladies whom are very involved in their philanthropy. And ADPis are kind of a hodgepodge of so many girls the sorority seems so big with so many types of personalities.
Rush week will teach you a lot about yourself and the sororities if you just go with an open mind. I'm so grateful to have had that unbiased experience. That is how you really end up in the sorority you fit in with best.
