I am applying to the SFSU BSN (on-campus) too. I can't tell you what you chances are but you certainly sound competitive, especially with your languages. Just to compare:
GPA about 3.7 overall, 4.0 in pre-reqs (or 3.8, depending which Chem I have to count
I did really well on my TEAS and got 94. I definitely recommend you take another try at it.
I have over 100 hours volunteer at a low-income family practice clinic. (I think they need a minimum of 100 hours to count it. Can you volunteer 20 hours before the app deadline?)
I'm fairly fluent in Spanish, as well as English of course.
The scary thing is that there are so many people applying. Have you been to an information session yet?
I am not applying to JC's (although they have great programs). Where else do you plan to apply?
