ΑΔΠ is considered a top tier sorority at USC, from what I've seen as an out of state student, simply by girls who are from South Carolina. It's a sorority that's been on campus for a very long time, and has a lot of history. Pledge classes are slowly degrading though. Last years pledge class was full of wild girls who repped badly for them, and this years pledge class is almost all blondes save for maybe ten girls. I'm not impressed. Very materialistic and judgemental girls. Cliquish.
