I'm going to rush next year too! I'm gonna be a sophomore. I wish I would have done it my freshman year. A lot of my friends did and I'm really bummed I missed out on so much. I don't know about UCSB but UCLA has a lot of really good sororities. The tops here are Alpha Phi, Kappa Kappa Gamma, Kappa Alpha Theta, and Delta Gamma. It just depends on who you mesh with best. Good luck!
