I only sent one recommendation when I applied EA. Is it possible to send another one to be considered in the RD round?
I think so, and that could be a very good thing for your application. I’d send an email or call admissions, though.
Just for anyone else wondering, I logged into my Georgetown application again and it is letting me add the second(optional) recommendation now. It previously was locked after I initially submitted for recommendations with only one, but I guess it opened up for the RD round again.
