Admins can set a school-wide deadline for making reservations, beyond which practicals will be marked as 'late'.
- Navigate to Settings > My school
- Specify either:
- a number of hours' notice required for reservations (type '0' to disable this deadline), under 'Hours notice required for reservation'
- a day of the week and time, beyond which reservations for the following week will be marked as late, under 'Make reservations made after <<time>> on <<day>> for the following week as late'
- Late reservations will appear in yellow in the scheduler
