Advisor - More lessons than days
If you have 5 days and define, that Math lessons shall be 6 times per week, the software will try to put at least 1 Math lesson on each day.
So your lessons will always end up like 1+1+1+1+2.
However for some schools this is not exactly what was needed, there can be two problems with this input.
1. The software will not try to place Math lessons consecutively. If you require the Math lessons to be placed consecutively, it is better to define the lesson as 4 single lesson and one double lesson.
I want to have Single AND Double lessons of one subject! E.g 1+1+1+2
2. Second issue can be that you allow more flexibility here. Maybe 2+2+1+1 is also correct solution for your school. But since the software treats 6 always as 1+1+1+1+2 you may be limiting options for the generation.
I want to have 1+1+1+2 OR 1+2+2 lessons per week.
