Likely your junior status alone was enough to get cut from some chapters.

But do keep this in mind. 1-you can have a quality sorority experience in any of the sororities on campus. If you really want to go Greek, you're going to have to accept that one of these bottom two is your only choice, and that's IF they continue to invite you through the process. Even if they're small doesn't mean they invite everyone back every round.
2-the houses that you loved because you connected well with them and they seemed to like you are REALLY GOOD AT RUSH. Every girl there walks out feeling like they had a great connection with that chapter. It's because they are so good at the game. Their goal is to have every girl like them so they get to choose who they keep and not give the power to the rushees. Give your last 2 a chance. You will still get the awesome Greek experience and a lifetime of sisterhood. Since you are a bit older, I'll suggest something to you that I wouldn't to freshmen: go to their national website and check out what they say about alumna. It might give you a fresh perspective.
