What are my chances of getting into UCD, UCSC, CalPolySLO, and San Jose State?

<p>Hello. I am a senior in high school who has 3.9 weighted (3.6 unweighted), a score of 2055 on the SAT, and a 31 on the ACT. I took Honors Chemistry (only honors class in my school btw) and AP Euro History in my sophomore year. In my junior year, I took 3 AP classes (APLanguage, APUSH, and APCalculus). I passed all of my AP exams. I am a member of CSF, co-leader of the chess club, an active member of the guitar club, a volunteer at a hospital , and a swimmer from my school swim team. I have over 50 hours of volunteering and community service. (Is this enough or shall I need more?) I live in California and I want to major in computer science & engineering. So what are my chances of getting into the colleges listed in the discussion title? (Yes, those are all colleges in California and that are my first choices.) Thank you!</p>
