may i ask what school you transferred to? only because I know things in the west/south are a little different than up north where i am...
personally, dont let your grades hold you back from doing something you want to do. YOU ONLY LIVE ONCE! and maybe even joining a sorority will help your grades and help you become more outgoing,
if those are things your worried about. find a group of ladies who are accepting and arent snots who claim your not smart enough to even
consider joining.
personally, i have grades most likely around what yours are and i am a proud member of a Greek organization myself, dont let anyone or anything hold you back. BE YOURSELF and have fun, my organization has helped me see that if someone doesnt like you for who you are, then screw 'em (sorry to be so blunt!) and you can find a group who does.
GOOD LUCK! I hope you find a group of people who your comfortable with and can have a lasting bond with also.
