I already have courses on my dashboard that I am using this semester. When this semester ends, do I have to create an entirely new course, and can I un-enroll the current students and add the new ones? I would hate to have to have tons of courses under "all courses" that I am not using. Yes, I understand that I can go to "all courses" and check or uncheck the stores to change what displays on my dashboard, but why have all of the old courses if I am not using them anyway. Thanks in advance!
