sorority ranks differently

Only at Duke do you see sororities trying to rip each other's throats out over the difference in one little placement in the ranks, as we have seen in the Pi Phi Kappa fight this year as they compete for a meaningless higher ranking. Here, I rank the sororitys in tiers, with (of course) noticeable differences between sororitys but overall similarly attractive and social girls in one tier. Most other schools do it this way.

Tier 1: Tridelt, Kappa, Pi Phi
Tier 2: Aphi, Theta
Tier 3: DG, Zeta
Tier 4: ADPi, GPhiB
Tier 5: ChiO
