How can I create new lesson in Substitutions
If you need to create a new lesson, you can do it in menu "Main - Tools - Add new lesson":
At first select class, or joined classes:
In the second step you can specify, if this lesson is for entire class or only for some group.
Then you can proceed as with creating a standard substitution - you can choose teacher, classroom, subject and period. In case there are some collisions, program will automatically show them.
After finalization, you can submit it with "OK" button.
Sometimes it is easier to cancel the old lesson and create one or two new ones.
How can I remove the substitution?
