So I applied RD and never got an email from CMU saying they had received my application. Should I have received one? Also, is there an “application status” site I should have been notified about? I have emails from the Common App saying I had submitted (and payed) the app and writing supplement. But my last email from CMU was from summer of last year.
You can use the link on the admissions website to check the status of your application. You just enter your Common App ID, last name and date of birth. My son got emails because something was missing, so I am sure you are fine. You would have been notified if you were missing anything.
Did you get an email from common app when you sent in your application? For every school that you sent your application in (thorough common app), you should have gotten an email for it. I would probably double check if you have that email.
