How exactly and when does Northwestern notify of decisions?

<p>How and when does Northwestern University notify applicants of their acceptance/rejection/waitlist? Do they come in waves? Around what time of the month? Specific days would be very helpful. Do they send emails? Do they call you? Do they send letters in the mail only? All feedback is appreciated, thanks! :)</p>

<p>Last year, we got our admissions decision by email at the end of March last year. I work around the admissions office, and I'm pretty sure there are more admissions decisions to be made so I would expect decisions announced around the same time this year. Also, it was nearly impossible to find out your decision last year because the website was overwhelmed by eager applicants trying to see their decision</p>

<p>How do you check the decision? Will it just state it in the email or will you sign into something on the northwestern website? Thanks again!</p>
