i'm wrapping up my senior year and have decided to go greek in the fall!

my bestfriend's older sister is an alumnae to a house at the college im going to, and she's the one who convinced me to rush a sorority. so now it comes down to this, what can i do over the summer to prepare for the recruitment process? i have about a dozen friends already in the greek system, but all the advice i have received is along the lines of "practice meeting strangers", "learn to curl your hair", etc. Not very helpful if you know what I mean.
Do you all have any tips? Please and thank you!!
