Review tiers 1–10

  • Checklists are parent-judged.
  • Written items: verify against practice set patterns.
  • Standard text: Pythagorean, reciprocal, and quotient identities Sum, difference, double-angle, and half-angle formulas Product-to-sum and sum-to-product identities (optional) Solving basic trigonometric equations Inverse trigonometric functions: domains and ranges

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 |
