Question about UCLA transfer, summer semester, and financial aid. HELP!

<p>So I'm hoping to transfer to UCLA for the Fall 2010 semester. However, I know that they send out their admission decisions in late April. So if I get accepted, and find out in April, can I enroll for the summer semester for 2010? If so, that leads to my second question: I know that if you're taking the summer semester, you can live on campus, but I couldn't pay for it out of pocket. So would financial aid (Cal Grants, Pell, loans, etc.) kick in that early, or would it not be available until Fall? Thanks for any help!</p>
