If you know which school you are planning to attend begin by looking at each sororities core values. Many sororities have similar values, so this is not an impossible task. Then try to think of how you meet (or not meet) them. If you find you do not meet all of the values, find activities that highlight that value and involve yourself in that activity. The values are meant to make you a better woman so either way you benefit.
