it really doesn't matter

All of this ranking stuff in the grand scheme of life really does not matter. When you graduate no one will care what frat or sorority you were in. When you interview for a job you won't be asked what ranking your frat was. When you go on a date your college life may come up and you may throw in you were in Greek Life, but will not be an in depth conversation.

So the point is, focus on yourself and don't worry so much what other people think.
