bottom/mid only houses on the rise?

Middles on the rise:
XO- got a really cute pledge class, seem to be getting better at balancing partying with academics instead of all academics, but will take a while to get rid of that stereotype.
AGD- pledge class was very different than previous ones, upgraded with more social girls, will move up if they continue to get pc's like this years. fun and laid back like KD but with less drama/more down to earth.

Bottom:
AXiD has good girls, but nothing will change for them if they don't start making themselves more relevant
DZ has potential but will take many years to move up, as long as they slowly progress
GammaPhi they really are happening better than people thought, their top-teir worthy girls need to start creating their standards
