What are the different stereotypes??

The only guidance you need is this: wait until Philanthropy round to see which sororities are actually inviting you to rush them. Meet those members and see how your conversations go and if you vibe with them and then make your ranks accordingly. Rush is in person for a reason. The sororities are making their first round decisions over the summer and whatever you put down as a ranking at Go Greek isn't really going to matter much. You need to keep in mind that your ranks don't come into play unless more sororities would invite you back than a round allows, which is not really common for most pnm's. The sororities are making the decisions of who to invite back and you will be released by chapters you rank high and return to chapters you ranked low. A full schedule at any round is not likely so keep an open mind and trust your gut and don't listen to gossip. This is YOUR rush not anyone else's. If you really like one or a few chapters at Sisterhood then you need to tell them so to get to their pref because they can't read your mind and they don't ever see your ranks of them. And at Pref it is really important to let your number 1 choice know that they are your number 1, if you do have a clear number 1. Forget stereotypes, you will see it all and figure it out just fine on your own from among the choices you will have.
