Junior at University of Washington rushing '09

Hey! I will be rushing at the University of Washington this fall, and am very nervous about it considering that I had to list myself as a junior on the recruitment application. I say it in this way because although I am technically a junior (I will be getting my Associate’s degree this summer), I am only 19 and will need to stay at UW for an extra year. Should I find a way to inform the sororities at the UW of my situation?
