The "Year's planning in terms" window can be opened by clicking on "Modules | Multiple terms | Year's planning in terms".
The window has two segments. In the left segment you see a complete list of lessons at your school, in the right segment, you see an overview of the already distributed total number of weekly periods per term.
Number of terms
Enter in the "Number of terms" field, the number of terms you want the school year to be split into and confirm with the "Tab" key.
How to lock terms
There may be cases, in which some lessons are not to be scheduled in certain terms. Highlight the respective cells, and enter "-3".
If a teacher is not available for certain terms, you can easily select all lessons of the respective teacher by filter, and then lock them.
How to enter the total number of weekly periods
In the "Total" column, you need to enter the sum total of all weekly periods for every lesson which is to be scheduled across the terms. In the example below, about 62 weekly periods of the subject "AnPh" (Anatomy / Physiology) in class 1a are to be distributed across the school year.
If you already have entered weekly periods into the lesson window, and you want to import them into your "Year's planning in terms" then highlight the "Total" column and enter "?". Confirm with the "Return" key.
