How to Decline UMD Spring Offer 2019 on Coalition

Hi, so this is a weird question but I have a unique situation. I applied as a first-year student to UMD-CP for the fall of 2018 but got spring 2019 acceptance. I accepted this offer because my plan was to attend in the Spring. But now I’m starting at a different institution and plan to receive my associate’s there instead. How do I decline my Spring Admittance on Coalition?

You should probably call the Admissions Office
