What are my chances of getting into UC Davis?

I'm a sophmore in highschool and UC Davis 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 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 doing set crew for the spring play and trying out for badminton. Does that sound like enough? Is there anything else I should do?
