Error message

For class 5A, you configured more lessons (33) than the maximum possible (30). Check the already configured lessons, or modify the maximum time interval.

What causes the error

When setting up classes, you defined a maximum number of lessons per day. You can review these settings in the class configuration section:

If this class has a 5-day schedule, the maximum number of lessons per week is 6 × 5 = 30.

If you assign more than 30 lessons to class 5A, there won’t be enough available time slots, and this error will appear.

How to fix it

You have two options:

1. Increase the daily lesson limit – Go to the class configuration section, find class 5A, and raise the Max lessons/day value.
2. Reduce the number of lessons – In the lessons section, check the total number of lessons assigned to this class and remove any that exceed the weekly limit.
