If you drop a course before the end of the University drop/add period (Fall 2021/August 25), your charge will be removed and your access to the course materials will be revoked. If you drop or withdraw after the initial drop/add period, the student is responsible for ALL fees associated with the dropped course.
If you had a physical book and you picked up the book – you need to return it back to the bookstore by the add/drop period to avoid being charged for the materials.
