Can I get into the University of California?

I'm currently a junior with a 3.1 GPA and SAT scores of 1342. My GPA has considerably grown since sophomore year and I plan on keeping that way. I am going to retake the SATs and take the ACTs. I have 4 years of xc and 2 of track. Freshman year I did a good amount of community service but it's been slim since then. I go to a catholic high school and am interested in becoming a PA and have also thought about ROTC. Is this a realistic goal???
