Cal admissions are more holistic than, say, UCLA, but I don’t know that your stats at this point are at Cal’s level. Yes, definitely continue to work on your upward GPA trend and retake the SAT for a better score. I echo @lacazette9 - look at the mid-tier UC’s, especially Davis and San Diego. We are blessed in California to have such a range of excellent public schools - take advantage of in-state tuition if you can.
