top sorority vs ranking?

Top sororities have the lowest rankings because people are jealous, simple as that

literally just realized the top 3 sororities at ubc are rated the lowest on gr hahaha

You'll usually find more truth in the discussion posts than you will in individual sorority rankings. When there are negative rankings for sororities it's typically because someone who has a personal issue with that sorority decided to post something bad about them.

That being said, essentially everything on Greek Rank is biased based on whoever wrote it. It's anonymous, meaning that girls can make up crazy stuff that isn't even close to true about sororities and you honestly shouldn't judge based on this site. It's tempting, but don't do it. You'll find out for yourself during recruitment, and once you've joined no one cares what chapter you're in as long as you're having fun.

Since a lot of first years seem to care about this, yes, fraternities do tend to favour Kappa/ADPi/GPhi more, but every sorority pretty much does exchanges with every fraternity with the exception of AOII and AGD
