Direct links to every vocabulary check point (Study app) for Pre-A1, A1, A2 and B1 — https://study.flyer.us/vi/<check_point_id>. Scope: Academic-built content only (excludes teacher-authored checkpoints). Most links open unpublished/draft lessons — only the "Live" tag means it is reachable from the real Candy World path today.

check_points.name — mostly digitized from the "Academy Stars" coursebook series. Opening a link requires being signed in on study.flyer.us; unpublished checkpoints will render but are not reachable through normal in-app navigation.user_attempts and assign_tests on the production read-replica, snapshot 24/08/2026. "Top B2B" is the school/center with the most attempts on that checkpoint, not legal ownership — this academic bank isn't locked to any one customer. Attempt counts are complete for every checkpoint (no extraction timeouts).| Level | Checkpoint name | Content preview | Types | Parts | Flashcard | Live | Attempts | Top B2B (by usage) | Assigned | Link |
