What are my chances?

<p>I am a sophomore in High school and it has always been my dream to one day attend UC Berkeley. However, freshmen and sophomore year I haven't done so well, because of traveling that I had to do due to family issues. My grades were really bad this year, even with two honors classes (honors english and history, C's in both). I know it counts as a B if I got a C, but only shows up on my GPA and the letter grade stays the same on my transcript. Junior year, I am taking AP Bio, AP US Lit, and H/French III. If I do really good this whole year and senior year as well, what are my chances of getting into UC Berkeley?
I am also joining the track team next year, and am in a soccer league for the city and involved with many organizations.</p>
