The Add/Drop period


The add/drop period begins on the first day of classes.  After pre-registration has closed, the wait-lists become only a reference tool for faculty, and you will no longer see any active wait-listed course sections on your record.  We no longer process the wait-lists nor offer open seats through this office.

FALL AND SPRING: the two week add/drop period ends at 4pm on the 2nd Friday of the semester.
SUMMER: the two day add/drop period ends at 4pm on the second day of class.

All regular add/drop registration is done via WebAdvisor.  As usual, you must obtain the permission of the faculty instructor to register for the class. If the instructor agrees to give permission, the instructor will record permission via WebAdvisor.  Once this is done, you will be able to register for the course section on WebAdvisor, provided a seat is available.

If you need to add a class, or are hoping to get into a wait-listed class:

  1. Attend the first class and speak to the instructor. Ask the instructor to provide you with registration permission via WebAdvisor if the instructor indicates that seats are available.
  2. Once the instructor confirms that this is done, you may register via WebAdvisor.  Do register as quickly as possible so that the instructor does not give the seat to someone else.

All students can drop courses online with the following exceptions:

  • CORE-106 or 107 - See the Exploration and Discovery Office if you need to change your CORE section.
  • the last class for which you are registered.  If you intend to withdraw from all of your courses, you must contact the Registrar’s Office to complete this transaction.
  • overseas courses - you must contact the Overseas Office to to withdraw from overseas courses.

All registration transactions must be submitted by the end of the add/drop period.  Please note that for registration activity that requires a paper component, the end of the add/drop period is 4pm on the last day of the add/drop period.  However, registration matters that require only the use of WebAdvisor may be completed up to 11:59pm on the last day of the add/drop period. You will not be able to add or drop course sections after that time.

It is highly recommended that you verify that you have permission to register for another course before you drop your existing course.  If you drop a course and need to re-enroll, you will need to obtain permission of the instructor during the add/drop period.  Staff in the College Advising Center or Registrar’s Office can show you how to use WebAdvisor to verify you have permission before dropping your existing course. Watch a short instructional video: Swap! Don’t Drop!


Non-standard registration may require a paper form in addition to web registration.  Please complete the form including appropriate approval signatures and return the form to the Registrar’s Office before 4pm on the last day of the add/drop period. Such registration may include:


Instructor permission to add must be granted via WebAdvisor first. The student’s advisor must provide permission for the overload via the paper form. Due by 4pm on the last day of the add/drop period.

FORM: Overload Request Form


Involved faculty members must provide WebAdvisor permission. In addition, the student and both instructors must complete and sign the Time Conflict form.  (Please note that freshmen are not allowed to register for courses with time conflicts.)  Due by 4pm on the last day of the add/drop period.

FORM: Time Conflict Authorization Request Form


Registration by paper only.  Internship, Practicum and Independent Study forms may be submitted on paper at any time prior to the upcoming semester. More information can be found in the College Catalog.

Please know that all Internship and Independent study forms are due no later than the end of the add/drop period - 4pm on the last day of the add/drop period.   If you do not submit your fully completed form by that time, the Registrar’s office will not be able to register you for the course.

DON’T WAIT!  If your form is not complete and correct, your instructor and department chair will have to sign next to all changes.  Many faculty are not available on the last Friday of the add/drop period. 

If you have questions, contact Hayley Bentley in the Registrar’s office. 

Independent Study/Directed Study

Please note that during the summer semester, the add/drop period extends only to the second day of the session.  See the Academic Calendar for specific dates.
