A 1:1 course has five tabs: Home, Timeline, Content, Billing, and Settings. Settings itself has sub-tabs: Course info, Drip settings, Session booking, Accessibility, Learner Permissions, AI settings, and Delete Course. Several of these mirror institute-wide defaults but let you override them for just this one course — for example, Session booking here vs. the institute default in 8.1, and AI settings here vs. the institute default in 12.3.
This is a shorter tab set than a Group course's seven (5.2): a 1:1 course has no Landing Page, Leaderboard, or Sessions tab of its own, because there's exactly one learner and the enrollment wizard already scheduled their sessions up front.
