If you are a full-time UNC System student there is no additional charge for a course that you register for through the Language Exchange/EMAoL Exchange (it is covered by your tuition just as if you were taking it at your home campus, and there is no ‘billing’ for it from the host campus).
If you are a part-time UNC System student you will pay the home campus hourly rate for the course, and it will be billed to your home campus. If there is a specific class that you are interested in, you must check with your home campus registrar to confirm the course rate.
