People always like to hear "What made YOU choose to pledge ABC?" It gives them a chance to talk about their personal experience and the best things about their sisterhood. It may also help you when you think back on the answers you received in different houses. Where is the focus for the sisters? Does that coincide with what YOU want?
Another good one is "What have you personally gotten out of being an XYZ?" The answers might be very similar, since Greek life is pretty good all around, I must say
. Ask for some specific examples. If the girl says something like, "I've learned time management skills," ask her how balancing activities was before, and what specifically the sorority does to help, what skills are taught. If she says "My grades have gotten better," ask why. Did she get help from sisters with the same classes? Was it a specific scholarship program which the chapter has implemented?
Remember, you know yourself best, and you'll know what things work for you. It'll help you get an idea of the sorority's programs outside of the sisterhood and bonding. Those things are very important and precious, yes, but since every sorority will say it, it's good to look at other aspects. They may be more practical, but they are tangible, beneficial parts of Greek life, and it's good to know how each sorority goes about encouraging them.
