Academic terms (semesters) are close, but not exactly the same between schools. The academic term at your host school may not coincide with the academic term at your home school.
The host school's calendar will determine all start and end dates as well as breaks for the course. You are responsible for ensuring that you can conform to the host school’s calendar.
Your final grade from the host school might not be available to your home school until after the end of your home school's academic term. Therefore, you cannot request for the host school to submit grades early (you are responsible for making other arrangements or speaking with your home school registrar if you need the final grade to graduate on time).
The following dates are posted on UNC Online for each course listing: start date, end date and last day to register.
Additionally, after you register for a course, you can view and compare important dates for your home school and host school by clicking the "View Details" button.
