Did Harvey withdraw when he met with school officials? Did he withdraw when the press release went out? Did he withdraw from classes he already registered for in the Spring/Summer/Fall? The information that I've seen in the press (which isn't everything, admittedly) doesn't provide any details about the specific timing of the withdrawal. If Unga withdrew from Spring/Summer/Fall, he would still be allowed to finish Winter Semester. It is important to remember that it was a voluntary rather than mandatory; he probably worked out terms that would allow him to finish the semester.
