Hi all, I'm in my second semester at SFSU.
Lots of my classmates commute in from all over the East Bay, some from much further away than Berkeley. If you can take public transit (BART), it's a bit less stressful than driving. Some people carpool together. However, bridge tolls and BART fares can really add up, so unless it's a lot cheaper for you to live in Berkeley, you might want to consider living in SF (I do.) I take public trans, drive, or ride my bike, depending on the day.
It's really important to have reliable transportation for clinicals, too--even living here in SF, some of the sites are way across town from me, and shifts either start REALLY EARLY or end REALLY LATE. :)
Anywho, congratulations everyone! It was a year ago that I got my acceptance letter, and I screamed, I was so happy.
