What is the difference between a drop and a withdrawal?

A drop is the process used when you want to "quit" one or more of your courses but still remain a student. This must be done prior to the 11th day of a term. Courses dropped are NOT listed on the transcript.

A withdrawal is from the 11th to the 60% day of each term. Dropped classes are listed on the transcript with a grade of W. 

A total withdrawal is done when you want to drop all of your courses for the term. You are then no longer considered an enrolled student. This requires the student to complete and submit a total withdrawal card to the Registrar's office for processing.

Either of these actions have implications for financial aid, health insurance, athletic eligibility, etc.
