In certain circumstances, for example in combination with the course scheduling module or lessons that take place fortnightly, it may be desirable but not essential to schedule different lessons at the same time. You can define this condition here.
Access the Lesson sequences window on the 'Scheduling' tab, set the drop-down list at the top right to Simultaneous lessons and enter the lessons that are to be scheduled in sequence.
The difference between simultaneous lessons and coupled lessons is that the optimisation tool is permitted to split simultaneous lessons. Coupled lessons, on the other hand, can never be split.
Converting lesson sequences into couplings
In the 'Lesson sequences' window you now can convert those sequences which are marked as ‘simultaneous lessons’ into couplings by one click. If these lessons have lesson groups assigned they are migrated into the field 'Lines lesson groups'.
