I'm wrapping up my second semester in the RN program at CCSF. Maybe I have a little bit of information for all of you considering commuting. (I don't actually commute myself, however.)
There are many students in my class that commute to the city for school, some from as far away as Novato and Santa Rosa. It can be done, but you have to think about the picture as a whole. The student who comes from Santa Rosa leaves for school at 4:30 in the morning.
Clinicals during the first semester are two days every other week, broken up into two groups, A & B. Group A goes one week for two days, group B goes the next week, etc. You have to be at the hospital at 0630, and they definitely frown on tardiness, so take that into mind. Also, for first semester, you go to the hospital the day before your clinicals to do your pre-lab work. The hospitals we went to for Fall 2009 were CPMC, General, St. Lukes, Davies. Not sure if they have changed or not.
First semester of CCSF will rock your world. It will run you into the ground. It's possible to have a tiny bit of a life, maybe. It can be done by commuting, but you need to take all that time and energy into consideration for your lifestyle. It may be worth it to just live in the city. And yes, BART is very expensive.
