While in your planbook, click "Settings & Schedule" at the top of your screen. Then, click “Adjust Schedule.” You will see any classes that you created in the "Create Classes" step. Click and drag a class to reorder your classes. Turn classes off for any day of the week that you do not teach that class. All changes you make will automatically show when you return to your planbook.
Note: We don't have A/B schedules yet, but we'll be working on them during the 2017-2018 school year. We definitely understand how important they are!
