If the transfer student did well in the CC, and then did well in the UC it doesn't matter. I did way better at UC Berkeley than at the CC. I also took the second half of my premed requirements at UCB, physics and Ochem plus a ****load of science classes in which I acheived an even higher gpa than at the CC. Now if someone takes all their pre reqs at CC it doesn't look so good or if they do really well at the CC then mess up at the UC. But most often, I see transfers the most dedicated students at my school. I feel like they mature faster and get serious earlier in life than people that go straight to a UC. Freshman are so annoying.
