I am in the exact same boat and I plan to take one year's worth of classes at SF State. I calculated that a full year of all A's would only bring up my GPA by about .1 but my UC pre-med advisor said if you can pull it off and give a good reason for why you didn't do well before ( ie worked a lot, health problems...) your one year at state speaks volumes to adcoms. Do it!
Also, I was an MCD major, so I felt like I took the same cell bio class over and over again. I plan on taking relevant pre-med classes like phys and immunology...
