isn't informal post-bac especially at cal state just taking classes through open university?
I don't think no one can tell you what you should do as no one knows what your stats are and what field you're aiming at.
CSUEB and SFSU have formal post bac programs for pre-health students, and there are some career changer programs in So-Cal that you can look into.
I mean, you have to specify which program you're looking into.
