Log into the Nest and follow the step in the Registration Tools on the Classes and Regitration page.

Students may add and/or drop courses through the end of the Add/Drop period at the beginning of each semester. The Add/Drop period typically extends through the first week of class (see the academic calendar for the official date). Schedule changes made during this period will not appear on a student’s transcript.


After the Add/Drop period ends, you may no longer drop a course, but you may be able to withdraw from a course by completing the paperwork to receive a grade of W in the course with the written approval from the Dean’s Office. Procedures for withdrawal are available here.

Fall semester registration for first-year students:
To add or drop a course, you are required to use the Registration Changes form. You must meet with your faculty advisor to discuss proposed changes and obtain his/her approval and signature.

All other students who have registered for classes on-line:
Go to My SJU to add/drop classes after discussing changes with your academic advisor. The PIN for CAS students changes during the Add/Drop period.

Important Reminders:

  • If you are attending class, but your name does not appear on the instructor’s class list, YOU are responsible for adding the class to your schedule. Even if you think you registered for the class, resolve the problem prior to the end of the Add/Drop period.
  • If you are attending a different section than what appears on your schedule, YOU are responsible for dropping the incorrect section and adding the correct section (assuming seats are still available).
  • If you are not attending a class, but it still appears on your schedule, YOU are responsible for dropping the class before the end of the Add/Drop period. After the end of the Add/Drop period, you will need to withdraw from the course (with a “W” on your transcript). After the deadline for withdrawing from a class, you will receive an “F” for the course.
