How do I book a student into a make-up class?
From the student's make-up right: pick a suitable session in another class, and the student joins that session as a make-up attendee. The target class's capacity is checked at booking time, so a full class cannot be overfilled.
Parents are told the make-up schedule through the message channels, and the session appears in the child's schedule in the Parents Portal. If the student attends, the right is used; if absent, it is burned; if excused again, the booking is canceled and the right returns to available while its deadline holds.
