Course Highlights

Below are examples of courses that have been open to auditors during past terms. They illustrate the breadth of subject matter and caliber of instruction auditors have access to at Columbia.

  • Auditors may not concurrently enroll in courses for credit.
  • Audited courses may not be repeated for credit.
