This may or may not have been answered before, but your GPA resets to 0.00 when you transfer, right? I have a 3.72 right now, but I may be getting my first-ever C in a 4-unit class (one of the last phys. sciences left for me this last semester, needed it for my IGETC but I'm awful at it).
Also, if you go on to grad school, do they want to see your comm. college GPA, or are they primarily interested in what you get after you transfer? I doubt one single community college C will really make or break my chances at a Ph.D program, but I want to cover all my bases.
