What are my chances of getting into UC's with a 3.71 GPA + AP's + ECs?

My weighted GPA at my school is a 3.8, unweighted is 3.5, and UC weighted is a 4.1. I am a junior in high school (in the top 12% of my class) and I have taken a total of 6 AP classes so far (AP Physics, AP Lit & Comp, AP Psychology, AP Calculus BC, AP World History, and AP US History). I’m planning to take 3 more AP classes next year in my senior year. I obviously don’t get straight A’s, but I also don’t get any C’s, D’s, or F’s. I’ve gotten B’s in some AP classes due to the rigor of the courses. I’m a year ahead in both my math and english courses, so right now, at my school, the courses I’m taking for math are designed for seniors, not juniors.
I’m on a sports team and have been on the team for all 3 years and plan on being captain next year. I’ve also done a considerable amount of hours volunteering at animal shelters, homeless shelters, and for clubs at my school. Also, I’ve taken the SAT once and got a 1300 but plan to take it a couple more times in hopes of scoring higher than 1350.
My main choice of universities is UCLA. I’m also looking into UC Davis, UC Irvine, UC San Diego, and UC Santa Barbara. What are my chances of getting into these colleges? I also want to go into medicine, so what are the chances of me getting into the nursing program at UCLA?
