How can I increase my chances of getting into UCLA?

I'm a sophmore in highschool and UCLA is my dream college. (: My grades are just okay (I got all A's freshman year, exept for a B in Geometry second semester and a B in PE) and am commited to getting straight A's this year as well. However, I don't have many extra-cirruculars. I take dance lessons and voluteer as a tutor after school. I'm also secretary of GSA, co-president of SRVC and a member of both JSA and another community service club at my school. I'm planning on trying out for badminton. Does that sound like enough? Is there anything else I should do?
