Yesterday (5/2) 4:30pm/EDT, my son also admitted off the wait list. and he accepted instantly through the email back, and so AO emailed very shortly with detail of the next step. and said official package mailed as well (also mentioned you will see your decision on your WashU Pathway account after 5:00 PM CST tomorrow 5/3) and will be arrived by Thursday. My son applied to College of Arts and Sciences.
