No, but the system allows you to skip, postpone or delete lessons.
• Skip means that you choose not to teach a particular lesson at all. Skip will remove the current lesson from the schedule and shift the next available lesson up to the current week you are skipping a lesson.
• Postpone means that you delay teaching the lesson one week. The system will shift the current lesson down one week. You're still going to teach it, but it's put off one week while you focus on something else.
• Delete will remove the lesson completely and nothing will be taught that week in the calendar. Skip shifts the next lesson up; delete leaves the week open/empty/blank.

Reverb is designed with 6 eight-week courses. You can rearrange the order of the courses, but the lessons within each course are set.
