After the drop period (midpoint of a given term) has passed, students may submit a petition for a late drop of a course only if serious extenuating circumstances exist that have impacted their ability to be successful in the course. 

Few exceptions to the official drop deadlines are granted. For consideration, you must follow a formal petition process in which you demonstrate that extraordinary extenuating circumstances, particularly those after the official drop deadline, have had detrimental and irreversible effects on your academic ability. You must submit a written explanation of your situation as well as supporting documentation (a doctor’s note, legal paperwork, an obituary, etc.). If you believe you qualify for a late-drop exception, you should talk to an academic advisor, who can provide you with the official late-drop petition form. Courses approved under the late-drop petition process will show as "W" on transcripts.
