mixing

greek rank is a website that should theoretically work when greek life on campus is a lot bigger. For UMass greek life isn't that big, but it still is a great organization and i highly recommend joining. With that being said Greek rank will never work at Umass because on all of the self ranking, and fraternities and sororities trying to ruin the reputation of other fraternities or sororities. This results in the lower grading of many good organizations, and higher grading of some of the worse. What i'd advise you to do is get to campus and take a look at all of the greek life on campus and choose the one with the brothers that you like the best. Don't let a stupid website make the decision for you.

Pretty much the four relevant sororities (Kappa, Aephi, SDT, SK) hang out like this

Kappa - Pike
Aephi - Pike and Aepi
SDT - Aepi
SK - Theta Chi

^the post above has it right for who those sororities are closest with

But it's UMass, to act like a sorority only hangs out with one fraternity is so far from the truth. The Greek community as a whole is very close. Kappa also hangs out with aepi a bunch, aephi also mixes with ZBT sig Ep and theta chi. SDT goes to pike phi sig and theta chi sometimes. SK will mix with both pike and aepi too. And the list goes on. Join a sorority or fraternity for the people in it because who hangs out with who can always change.
