Your school is the place you sign in to; your enrollment is your participation in one program. It determines which path, tasks, deadlines and spaces you can use. If you have more than one enrollment, choose the one you mean to work on: progress from one is not mixed into another.
Imagine an illustrative member of Mike Academy's Agentic AI Developer program. After the school records their enrollment, a person at the school sends a separate invitation. The member activates their account, completes onboarding, opens a lesson, builds an agent demo for a published task, sends a link for review and asks a question in their program space. The reviewer asks for one change; the member sends a new version. These are example events, not a claim about any particular member's record.
A coach or reviewer approaches the same enrollment through a different role; see Coaching. For the complete task and unlock rules, see The member journey.
