Adding exceptions to your school schedule can happen all the time, and the Studyo planner supports this by displaying a red triangle in the corner of conflicting periods. By default, it can't decide which period to display above others but clicking that red triangle allows users to select the right one.
There are situations where it can favor a period over another:
One of the periods is marked as high-priority
Other periods are marked as skipped
Teachers can mark periods as skipped from their "Teacher" view in planner, and that's an important feature to learn about, but in some situations, for example when adding an exam period for a whole level, you can't rely on each teacher skipping their respective periods. Hopefully, Insights also allows you to skip periods, via the "Manage schedule conflicts" on a section.
The idea is to pick the section that introduced the conflict, so you can skip other occurrences happening at the same time for any common student.
Here, the French exam, in the blue column on the left, is occurring at the same time as the first two classes of many students and slightly overlapping their advisory period. All those periods represent any section occurrence a student of the "French Exam" section has. You don't know which students, but you can trust that, for example, at least one student has "Latin I" on that morning at the same time as that exam period.
If you click that "X" symbol in a period, you get these options:
Selecting to skip class occurrences and shift tasks and notes comes with great responsibility. This has a big impact on that teacher's planning and should only be used when agreed with them. Most of the time, the first option is the one to use, so skip the occurrence without impacting tasks and notes. The teacher can later shift tasks and notes from their Studyo planner. In our example, selecting the first option results in this:
Ok, one occurrence skipped, many more to do... Don't worry, there's a faster way! Those two buttons at the top allow you to either skip all occurrences in conflict, or all occurrences on that day.
Let's try the first to see what happens.
Much quicker! This is a good example of a morning exam taking the place of regular classes, but normal classes resuming after it. If, on that exam day, students were released after it, we could have used the second button to skip everything else that day.
Also, those two options never shift tasks or notes. They only skip occurrences.
