If you've spent time customizing your MathXL course and want to use the same course next semester, you can copy your existing course and preserve all your customizations. You can also let other instructors copy your course. To coordinate across multiple sections of the same course, you can set up a course group, where assignments in the "coordinator" course automatically appear in the affiliated "member" courses. This option is ideal for departments that want to maintain a standardized syllabus across multiple sections taught by different instructors.
