Madam frequently cancels classes.

Madam frequently cancels classes. Sometimes, she schedules a morning class, but after the students arrive, she does not show up. Her course materials are also very disorganized. She often spends a lot of time telling stories or simply taking attendance during class, leaving very little time for actual teaching. As a result, she covers very little of the course content, which causes the number of lectures to increase unnecessarily and wastes our time.
