I don't think the women at AEPhi necessarily want you to learn their entire history and/or the greek alphabet. Recruitment is a time to get to know the campus women interested in joining a sorority. I think they would probably be more interested in learning about you and seeing that you want to share a sisterhood and help the greek community and have fun with them. I think you should just be yourself and show genuine interest.
The other posts are correct though in saying each chapter has a finite amount of bids they can offer and overall everyone is interested in making sure the women offered bids and the chapter that offers them fit well together.
Good Luck
