TL;DR
Optional classes combine a scheduled session with registration rules. Configure both before inviting students to register.
Steps
Open the relevant section in Insights with editing permission.
Configure its optional-class or registration options and eligible students.
Check session dates, times, capacity and the assigned teacher.
Save, then verify the registration option from an eligible student planner and the list from the teacher's view.
Do not assume that membership in an eligible group registers a student for every optional session. Check the actual registration list. Coordinate imported class settings with the school system that owns them.
In Sections, use the row’s three-dot menu: Edit details for section settings, Edit schedules for periods, and Manage conflicts when available. Clicking the section name opens its overview.
