@678triple98212 My son is in almost the same position, admitted to Honors but not invited to Banneker/Key. So we are also waiting on merit notification.
I love UMD as I have an older son already there, but all their websites listing different merit notification dates are almost comical.
First, their twitter page says notification electronically by March 1.
Then their admitted students FAQ https://admissions.umd.edu/explore/freshmandecisionfaqs.php has it answered twice in the same document, once March 1, once April 1.
And then their merit scholarships page says mid March. https://www.admissions.umd.edu/finance/freshmanscholarships.php
So I imagine one of these dates will be correct. Good luck.
