A few questions about CCC and transfering

<p>Hi all! I'm going to be a full-time freshman at Diablo Valley College for spring 2014, aiming to transfer to berkeley. I'm unfamiliar with this whole transfer process and have read up as much as I could about it but still have some further questions! Hopefully someone can help!</p>

<ul>
<li><p>I plan to take computer science as a major, and have checked out assist.org. DVC offers 2 out of 4 of the compsci 61series, which is more than most of the other CCs. However, if I want to take another course at another college, what do I have to do? Can I enroll in two colleges at once? Won't that affect my schedule? Or will the DVC administration handle it?</p></li>
<li><p>When I transfer to berkeley (fingers crossed), it says that my B.A would be CS (lower division)...is there any way to change that to upper division? Or do I have to just fulfill all the courses in the lower division and then get 'upgraded' to the upper division?</p></li>
<li><p>I slacked off in highschool but am determined to study hard in CC, I know I can do it. But I also know that GPA isnt everything, so what other things should I do? Can I juggle classes with internships/jobs as well as ECs?</p></li>
</ul>

<p>I probably have more questions, but thanks to anyone that responds!</p>
