Eve,
I am sorry you had a disappointing time with rush

. I was in graduate school the second year I was in my sorority and found that I had no time for my sisters or the sorority at all. I can't imagine being a pledge during that time period as pledges have a great deal of things to do every week (at least we did). I guess another good question to ask if you were to COB is all the requirements of a pledge and then realistically look at your program and see if you can devote enough time to both. Good luck with your decision.
