Review tiers 1–10

  • Checklists are parent-judged.
  • Written items: verify against practice set patterns.
  • Standard text: Identify questions suggested by patterns in data. Estimate probabilities using simulation. Calculate probabilities for events and their complements. Explain why two events are (or are not) mutually exclusive. Calculate conditional probabilities. Calculate probabilities for independent events and for the union of two events.

Practice test scoring

| Tier | Pass guidance | | --- | --- | | 1–3 | Most oral tasks smooth; majority of written correct | | 4–6 | 7/10+ total with clear understanding | | 7–8 | 9/12+ with explanations | | 9–10 | Near-perfect; ready to move on |
