What is crn in college?

CRN (Course Reference Numbers) are unique numbers assigned to each section of a course at a college or university. The CRN is used for registration and enrollment in a specific course section within a given term or semester. CRN includes key information such as the course code, section number, and start and end dates, which help students identify and select the right course sections they need to register for. The CRN can also be used to track attendance, grading, and other academic records associated with the course. In short, CRN plays a significant role in student registration and enrollment process in college and universities.
