Congratulations on your graduation! You have a wonderful experience ahead of you.
As for your question, Alpha Gamma Delta is looking for young women who are being themselves! Your unique personality should shine through--don't try to be someone you're not in order to impress. I've always thought that genuineness will get you far. If you're a fit with the chapter both you and they will know it!
Of course, it never hurts to have a good GPA and interesting extracurricular activities. But, remember, just be yourself!
Good luck with rush. I am so pleased that you are interested in Alpha Gamma Delta. Keep in mind, however, that all sororities have something very special to offer--so keep your options open.
But, I hope that we can call you a sister soon!
