Though both terms technically refer to leaving a course, they typically are used slightly differently. Dropping refers to leaving a class early on in the semester, usually before the “Add/Drop” period ends. Typically, dropping a class comes with less complications and is more common. Most of the time, if a student drops a class, they pick up another course in its place. \r Withdrawing occurs after that period has ended, and when the possibility of adding another course has passed. It is in these situations that enrollment status and financial aid can be most affected.
