All of those are review committees. If I remember correctly (and I know I am not 100% so correct me Judi) but SRC I believe is a social events review committee and GARP is a standards review committee. I was asked to run for GARP but never got all the info.
Thats awesome that our house got so many positions. All of our total years on campus AGD's have always been involved on Greek Committees and Panhel has loved us for it.
Congrats to the Alpha Beta's! (Miss you guys)
