I submitted my application before the march 1st deadline but I forgot to send my transcripts in until last minute. I mailed my transcripts to umd feb 28, so im not really sure if they go by the postmarked date or the date when they received it. I am graduating this may 2020 and have a 3.67 gpa.
Their website says they go by postmark.
"Applications are considered complete when the online application and all required documents have been submitted. All materials must be submitted electronically or postmarked by the appropriate deadline for consideration. You can track your application status and confirm receipt of application materials online through your MyCoalition account by visiting the Colleges section and reviewing your UMD checklist. It may take up to two weeks for recently submitted materials to be listed as received on your checklist and it is the applicant’s responsibility to confirm receipt of materials through MyCoalition. "
