Error message

For class 7B, there is an odd number of non-weekly lessons.

What causes the error

When configuring non-weekly lessons for class 7B, the number of lessons isn't balanced across weeks. For example, in a 2-week timetable:

• Music – 1 non-weekly lesson
• Art – 1 non-weekly lesson
• Theatre – 1 non-weekly lesson

This results in an uneven distribution — one week will have more lessons than the other, which is not currently supported by the application.

How to fix it

Go to the lessons section, search for the class mentioned in the error message, and adjust the lessons so that each week has the same number of non-weekly lessons.
