The letter from the college wasn’t skinny, but it wasn’t fat either. It was somewhere in the middle–you’ve been waitlisted.
What landed you on the Waitlist
People are put on waitlists for a variety of reasons, the most common of which is that the admissions committee really liked you, you were a compelling applicant, but there were simply other applicants who were stronger. You were likely a student they knew could do the work and would have contributed nicely to the campus community, but again, other applicants had higher numbers, higher grades, more significant activities, etc. In the end, you’ll likely never know what got you on the waitlist or how close you were to being admitted, or denied, so don’t spend time ruminating about it. As the adage goes, “It is what it is.”
