Where to find this: course → Sessions tab → Schedule Sessions, or Settings → Tutors

Unlike a 1:1 course, which schedules sessions as part of enrollment (4.1), a Group course's Sessions tab starts empty — sessions are added separately. Schedule Sessions opens a form with Learners (pre-filled with whoever's already enrolled), Session name, Tutor, Duration, Location (Live / In-Person), and a calendar to place sessions on.

This is also where a tutor is actually assigned to a Group course's sessions: a separate, empty-by-default Tutors list sits under course Settings ("No tutor added"), distinct from picking a tutor ad hoc on this scheduling screen. Formally assigning a tutor to the course happens in Settings → Tutors (5.8); picking one here governs just the sessions being scheduled in this pass.
