@astro77 and @lifegarding , thank you so much for your responses. Very helpful. My best wishes as well
Just following this thread for my S18 - sounds like others also did not receive an e-mail ack that the College Park received the application via Coalition? )Common App so far has sent an e-mail.)
I asked UMD that question. They said they do not send an email confirmation. We need to check on the coalition portal.
