Regarding UCSC, I was able to get a subtle idea of my position on their list of applicants. I told them I was beginning to visit schools where I was accepted and was hopeful they might share their decision to make my decision easier (because, my god, why is it taking so long??). They were very clear that NO decisions were finalized, but did let me know I was not in their pool of top contenders, but then reiterated that I wasn't being denied or accepted and that no final selections have been made. So, I'm not sure if contacting them was even very helpful. Just thought I'd share the news.
