Honestly I can’t believe how dumb I was....
Somehow earlier tonight I decided to reread through my grad school application for the university that I will be attending this Fall (bad move to begin with). Then, I realized that I had put the wrong month for the date that my undergrad degree was awarded, i.e., May 2018 instead of April 2018. However, the correct date was shown on the transcript that I had attached with my application.
Should I email the admission coordinator about this?
