Each class offering of any course has its own unique identification number.
This is referred to as the CRN (or Course Reference Number). Typically, the CRN consists of 5 digits for Spring or Fall semesters and 4 digits for summer semesters.
For example, you might register for a fall section of an online Accounting 101 course which has a CRN of 20001.
This schedule is for paper tests only. If you are an online student, please check your course syllabus to determine whether you should follow this schedule.
