Each track is 10 to 14 scenarios graded against the same five-dim rubric. Start anywhere: the first scenario is free without an account. Every track ends in the same place: a cert and a recruiter-readable profile page.
A track is not a quiz pile. The scenarios layer: scenario_01 builds a habit, scenario_05 tests it under time, scenario_12 puts the habit against a constraint. Everything is graded by the same rubric. If you wash out at scenario_07 we tell you which dim, then point you at the learn-hub video that fixes it.
A track is labelled by the candidate it expects. Entry tracks meet first-job folks; mid tracks meet someone with 1-3 years in a real role; "all" tracks layer both. We do not ship a senior band: senior is a posting concept, not a track concept. Recruiters set seniority on their side; the same rubric grades everyone.
Choose a scenario that reflects the role. Inspect the environment and evidence; a track name alone does not establish job readiness.
