If a student is absent in class, you can mark their attendance in the game to exclude them from events such as:
- Random events
- Team point gains/losses
- The Wheel of Destiny
You can find this option on the "Class" or "Teams" view of the game dashboard in the "Absent" column.
Marking a student absent won't exclude them from entries in the Grade Converter. Attendance is not saved or recorded long-term.
