Waitlist Chances for Class of 2021 - Northwestern University?

What are the chances that students on Northwestern’s waitlist will be reached before May 1st?

None. May 1 is the national decision day deadline. After the school sees how many people committed to attend, then they go to the waitlist to fill and “holes” in the class. Your best bet is to commit to the financially feasible option that you have now. Attend admitted students days and get psyched about your school.
