On the website, they say that Early Action applicants will be notified online by Feb 1, and they have you create an account for their online portal. However, the list of portal uses says nothing about seeing your decision on the portal. I would like to know if Northeastern sends out decisions via email, on the portal, or in a physical letter.
All three. Portal / Email around the same time (email to alert you on the portal, usually about an hour or less after it becomes available) and then followed by a letter/acceptance package in the mail.
