What is a course code? A course code is a combination of letters and numbers that you enter to enroll in your instructor's class. Each instructor has his or her own course code (or codes, if he or she teaches multiple classes). Your instructor will give you the appropriate course code. Once you have received the course code, go to the home page and log in. Then, enter the course code in the field next to your book. Need more help?
