Second, FYI the Degree Audit is programmed to often pull the most recent course that fulfills a requirement. In addition, in response to student requests, the Audit is now also configured to show planned, waitlisted, and registered-but-not-started courses to help students more efficiently plan and review course selections.
OK great, but what if I drop a class that the Degree Audit thinks I'm going to use to fulfill a Foundations requirement?
If a previous course was approved for this requirement, the past course will go back to where it was and the requirement will be fulfilled once more. It's a good idea to check after dropping a class to make sure this happens. If it doesn't, use this form to request an update to your audit: https://slate.barnard.edu/register/degree_audit_changes.
