You can use the <Suggested swaps> button on the 'Start' tab to automatically display how the active period could be swapped within the class and across classes. To this end Untis evaluates the timetable based on your weighting settings and indicates if the quality of the timetable would be better or worse.
With class leaps
It is often necessary to perform swaps across several classes. In order to enable a swap to be made in one class it is first necessary to perform a swap in another class - the so-called leap class. If you check the option 'With class leaps', these types of possibilities to swap will be offered.
The above example shows that the swap in class 1b would result in a 24-point improvement, therefore a swap in the leap class 1a is possible which brings about a highly ranked improvement, since a lesson scheduled on a locked period can be swapped.
The timetable in the above examples will clearly be improved.
