blueballz.... it depends on wat frat u wanna join... 1. if its social, then prepare to be destroyed and fail some classes
2. it its professional/community service, then it depends on whether you are gonna get anything out of it....
I'm in a professional frat and i've have to admit that my grades went a little down but not failing... but throughout rushing, i learned how to manage my time and stuff like that... so i feel better off now...
All Frats are gonna tell you: don't join just for the connections, join because you want to join and you believe in the frat...
