I do not want my geography to be on Friday and then on Monday

The program automatically puts your lessons equaly over the week, not on consecutive days.

However by default Friday and Monday are not consecutive days. So if you do not want to have the lesson on Friday and then on Monday you have to define an advanced cardrelationship. Please check the following picture:

It sets that Geography lessons in all classes can be on max one marked day, be it either Monday or Friday.

It is important to choose the right card relationship:
"Max. number of days that have lesson on marked position"
and also the
"Apply to selected subjects in selected classes"
option in second combobox
