Based on personal experience, I think it is important not to overload on your first semester or trimester at college. I would suggest taking the minimum full time student load that first semester or maybe add in one class of interest that is less that a full credit class (maybe it is1 unit instead of 3). Perhaps a sports class, drama, or film. Pick an area of interest. For the courses that make up your full time student load, make sure those are your core general education classes. Being a commuter takes a little extra time so factor that in accordingly. That "extra" class might give you an opportunity to connect with other students with a common area of interest. I was a commuter kid and know that connecting with others on campus is important for a sense of camaraderie and belonging.
