In the previous example we specified that GA should take place in week A and DS in week B and that these two lessons should be scheduled simultaneously if possible.
However, you can also assign several lesson groups to one lesson with the system then deciding during timetable optimisation
a) which of the lesson groups concerned is more suitable and
b) which lessons can be scheduled simultaneously without a collision occurring.
This means that you only need to tell the system which lesson should be scheduled every two weeks and it does not matter whether week A or week B comes first and which lessons alternate every fortnight. The system should make the optimal decision.
The procedure is described below:
A number of lessons are held in a fortnightly cycle at the school - e.g. the subjects DS, GA, GEc, SPORT etc. It really does not matter in which week a particular lesson takes place.
Create two lesson groups again, one for week A and the other for week B. Please refer to chapter 'Creating Lesson Groups' for more detail on how to do this.
Now enter both lesson groups (short names), separated by a comma, for the lessons that are to take place every fortnight.

Timetable optimisation will now assign the lesson groups and decide which lessons can be scheduled simultaneously.
After timetable optimisation the results could be as follows:
For some lessons lesson group “A” (week A) has been selected and for others “B”. The “Assigned Lesson Group” column will display which of the lesson groups in question has been selected for the lesson.

You can see in the timetable that as a rule the lessons alternate on a fortnightly basis. If optimisation does not find a suitable lesson for the alternate week the lessons are scheduled outside the core timetable so that one group of students finishes school earlier on the relevant day (Monday and Thursday).
