I mean, you definitely could email the admissions email and tell them that they’re your top choice, but they are very strict that an applicant cannot add anything to their file to be considered for admissions. So i bet it wouldn’t necessarily hurt, but I can almost 100% guarantee they will not consider it unfortunately. I was waitlisted to Davis last year and they were my top choice, and I emailed them once saying something along the lines of “I was wondering if you were able to disclose how frequently waitlisted applicants were accepted, as Davis is my top choice and I would 100% attend if accepted”. They emailed like 2 weeks later and basically said nothing except “it depends”. I was rejected later on lol, and I don’t think it was because I emailed them but obviously it also didn’t help much haha. With Davis, you are in it for the long run unfortunately. Good luck fellow applicant
