Revising Your Schedule

To make changes to your schedule online after you have already registered, go to the Add/Drop Classes section. If you have already registered for your maximum number of units, you must drop a course before you can add another to your schedule. Make sure to click on Submit Changes to process. Check the Current Schedule section to be sure your changes were successfully processed. All class restrictions, enrollment cap, etc., are in effect during schedule revision.

Additional Instructions

  1. Graduate students will register for graduate level courses ONLY.   These courses are 3 to 5 digits in length and begin with the number 3 or above.  Students must be registered for a minimum of three units to be considered full-time.
  2. Individualized Courses  Directed Study courses (A&S), Directed Research courses (SOM), and Independent Study courses (SPS) are created on an individual basis upon request.* Information will then be provided to the Registrar’s Office to create the course. You will receive an email from the Registrar’s Office containing the CRN number, which you will use to register online yourself for that course.  *NOTE: A&S students: email the faculty; SOM & SPS students: email your Advisor or Program Chair
  3. Variable Credit
    Courses that appear on the schedule with “Var” in the Units column are offered for variable credit (e.g., Directed Study courses are 1.000 to 3.000 units). A default unit (generally 1.000) will automatically appear in the credit hours field after you have registered for the course. If the default unit is incorrect, follow the directions below to change it. If you have questions about the number of units assigned to a variable credit course or are unsure of how many units to register for, please contact your department.

    1. After you have registered for a Variable Credit course, the “default” credit will appear in the Credit Hours field. See the image below. If this is incorrect, click the Change Class Options link at the bottom of the page.
    2. The Change Course Options dialog box appears. The default Credit Hours appears in the Credit Hours box.
