Lea,
Being from the bay area and being familiar (esp stanford, I"m from Palo Alto) with all the Cali schools that you applied to I can tell you that UC Santa Cruz only has one national sorority at the moment, (pi Phi I believe) so it shouldn't be too hard to find out the cost there since there is only one soror. I have some friends at Stanford who have told me going greek there is VERY expensive.. I'd say 500 a month or so. My friend at Berkely pays 625 per semester for dues and such. San Francisco State I can tell you EXACTLY what the three sororities there cost, because I go there and have the flier we give out during rush that has the exact prices listed.
Alpha Gamma Delta is 385 new member fees and 250/ per semester after that
Phi Sigma Sigma (which just happens to be the BEST sorority on campus IMO..
) is 285 new member fees and 350 for fall semester and 180 for spring semester.. (we pay our national fees in Fall, that's why they are higher) and
A-Phi is 350 for new members and 325/semester
I know at my chapter any event that's mandatory is covered by dues. We don't have houses at SFSU, so these expenses are seperate from the rather pricy San Francisco rent you pay to live in the dorms or off campus, however after reading some of the other replies seems like all the chapters on our campus are a bargain. If you have any questions about any of the schools I know people who go to all of them and can get you in touch with them or answer any questions for you GOOD LUCK on your transition to college next year and if you end up at SFSU I'll see you at open house !!!!
