Academic credit assigned to a course is expressed in semester credit hours. A passing grade on a subject that requires three one-hour meetings a week (or the equivalent) for one semester earns three semester hours credit. A laboratory period of two to three hours is equivalent to one class hour. When a student exempts a course requirement at Georgia College, the exemption includes only the subject matter, not the credit hours. The credit hours have to be made up by passing other non-exempt courses.
