What's the best way to prepare for Panhellenic Rush this fall ?

So after taking a year to really scope out all my options I've finally decided that I will be rushing Panhellenic this upcoming fall. I'm not too worried about the fact that I'm african american, because the sororities on my college campus are already pretty diverse. This question is pertaining to any greeks really, do you guys have any tips or any added advice I should be aware of ? Please and Thank you :)
