AP Calculus AB Units Guide: Complete Breakdown of Units 1–8 (2026)
AP Calculus AB is divided into 8 units — and understanding how these units connect is the key to scoring a 5.
This page gives you a complete overview of each unit, its exam weight, and links to detailed guides, notes, and practice strategies.
According to the official
College Board AP Calculus AB Course Page,
the course is structured to build from limits to applications of integration through eight sequential units.
📊 AP Calculus AB Unit Weightage
| Unit | Topic | Exam Weight | Guide |
|---|---|---|---|
| Unit 1 | Limits & Continuity | 10–12% | Read Guide |
| Unit 2 | Differentiation Basics | 10–12% | Read Guide |
| Unit 3 | Advanced Differentiation | 9–13% | Read Guide |
| Unit 4 | Applications of Differentiation | 10–15% | Read Guide |
| Unit 5 | Analytical Applications | 15–18% | Read Guide |
| Unit 6 | Integration | 17–20% | Read Guide |
| Unit 7 | Differential Equations | 6–12% | Read Guide |
| Unit 8 | Applications of Integration | 10–15% | Read Guide |
📚 How the Units Build on Each Other
- Unit 1 → foundation of limits and continuity
- Units 2–3 → core differentiation skills
- Units 4–5 → applying derivatives to real problems
- Units 6–8 → integration and advanced applications
This sequence is intentional — skipping early units makes later ones much harder.
🎯 Most Important Units for Scoring a 5
- Unit 6 (Integration): Highest weight
- Unit 5 (Optimization): Frequent FRQs
- Unit 4 (Applications): Interpretation-heavy questions
