advice about approaching members of the sorority

[pinkandgreenwish]

Hello divine ladies of Alpha Kappa Alpha sorority, I am interested in becoming a member. My grades are excellent, I am involved in a few clubs, and I have participated in some community service. The problem is I only "know" one chapter member (she is my roommate). If a member and I's paths happened to cross, I am friendly. However, I do not "brown nose" the members because I feel weird trying become friends with the other members just to get "extra points". Do not get me wrong these ladies appear to be nice, but since I have never actually had chance to meet them (such as organizations) I do not want to over do it. Should I try to gain better relationships with the ladies or should I continue with my actions? If a interested student isn't well known amongst the sorority members, what is the chance that they will be picked from the other interested girls?

Thanks,
wishing for pink and green

p.s. sorry I couldn't go into full detail like I wanted, its way pasted my bedtime and I can't think straight
