Just wondering, how are you a junior if you're only 18?
Anyway, check out San Jose State's Panhellenic website here:
http://www.sjsupanhellenic.com They even have the Fall 2010 recruitment dates posted if you click on "Recruitment" on the left side.
I don't know how competitive recruitment is there, and no one here can tell if you're going to get a bid or not. Check out the other threads here on GreekChat about going through recruitment and getting recommendations. Good luck!
