I'm not really sure where to find the student fee deduction, as it wasn't mentioned in my letter. Just an intelligent guess seeing your post. Do you have any link where I can confirm it for myself ?
I wasn't informed anything about listserv, I'm trying to explore the off-campus housing options with help from some senior brothers there in UCSC. I think you could use the same idea- pick some options in craiglist, or fb 'UCSC Community' and take opinions from people already there to judge the options.
