Registration: How to add/drop a non-waitlist course

← D&I / Electives
Follow the below instructions to add or drop a non-waitlist course during open add/drop periods in OASIS.
Add/drops will not be available when a lottery is in session.

To Add a Course:
  1. Go to OASIS (https://oasis.cumc.columbia.edu/).
  2. Click "Add Course" on the top menu bar.
  3. Search the catalog. You can filter by Department and other search criteria.
  4. Click "Add" under the Actions column.
  5. Select the desired month in the Add column, and click "Add Selected Course".
Note:
  • OASIS will not allow you to add two courses to the same month. You will need to drop a course before adding another course for the same month.
  • OASIS will not allow you to add the same course twice. If you are trying to switch which month you are taking a course, you will need to drop it first before adding it for the new month.
  • OASIS will not allow you to add or drop a course within 28 days of the rotation. Please see our instructions for late add/drops instead.
To Drop a Course:
  1. Go to OASIS (https://oasis.cumc.columbia.edu/).
  2. Go to your schedule.
  3. Click "Drop" in the Actions column for the course you would like to drop.
