At a glance

Too many lessons have been assigned to this group — there are not enough time slots.

What causes this error

The total number of lesson slots configured for this group exceeds the maximum number of available time slots. The maximum is determined by the group's time range (earliest start, latest end) and the number of school days.

For example, if a group has 6 periods per day across 5 days, the maximum is 30 slots. Assigning 33 lessons is impossible.

How to fix it

1. Reduce the number of lessons — Go to the Lessons section and remove or reduce the frequency of some lessons for this group.
2. Expand the time range — In the class configuration, increase MAX_TIMESLOT or MAX_PERIODS_DAY to allow more daily slots.
