How to use the 20 practice sets

| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |

Pacing: 10–15 minutes per session.

How to practice

1. Sketch graphs to check signs and behavior 2. Label u-substitution clearly 3. Interpret derivatives and integrals in context

Common mistakes

  • Algebra errors after differentiation
  • Forgetting +C
  • Misapplying L'Hôpital

Review and practice tests

1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for Parametric Equations, Polar Coordinates, and Vector-Valued Functions.
