what are the real sorority rankings here?

There are no real rankings at wise. Honestly it's just about where you fit in best at this school.

If you had to rank it would be:
Theta Phi Alpha (top)
Phi Sigma Sigma and Alpha Sigma Tau there is an argument between which is better than the other some people put Phi Sig as number 2 others put ast as number 2

I agree with the other girl. The sororities are different enough from each other that it really comes down to how you fit in.
I think Theta Phi has had the top for a while but is now grappling with Phi Sig because of that awards banquet. AST is improving their reputation some, because it used to be pretty bad, and they are getting more involved but they slip up sometimes and piss people off.

Honestly, I don't see how you can rate the sororities. Each one brings different things to the table. They all love their each individual sorority. They're too different to even attempt to compare.
