<p>I was waitlisted last year (Columbia saw a record number of applications). The waitlist was pretty big too, if I remember correctly. The way the waitlist at CU works is they try to fill a spot of the person who didn’t accept. For example, if a violin playing biologist dropped out, then they would look for a similar applicant to fill that spot. You guys also won’t hear back till mid-May most likely, but DEFINITELY write the extra letter.</p>
