statlanta, I agree with you for the most part. However, though the OOS admission rate is higher at Berkeley, for instance, OOS also is a stronger applicant pool, so the average SAT scores are actually higher for OOS acceptances than for in state acceptances.
Still, I don't think there is much difference between being an OOS applicant and an in state applicant for UCs, at this point.
My gut reaction is that you have a pretty high chance of getting in the UC's but Stanford is a reach, due to a low amount of ECs. With that said, I urge that you DO NOT completely trust my assessment, considering that I'm just another high school senior myself. In addition, there are vital pieces of information that are either missing or impossible to judge on CC chance threads, including whether or not you are an URM, the strength of your essays, and the competitiveness of your high school.
Best of luck!
