AP Calculus AB Study Guide: Key Concepts for the 2026 Exam
AP Calculus AB tests your understanding of limits, derivatives, integrals, and the Fundamental Theorem of Calculus. Here’s how to focus your preparation for the 2026 exam.
High-Priority Topics
Limits and continuity form the foundation — make sure you can evaluate limits algebraically and graphically. Derivatives dominate the exam: know the power rule, chain rule, product rule, and quotient rule cold. Integration follows, with emphasis on definite integrals, area between curves, and accumulation functions.
Free Response Strategy
The free response section tests multi-step problem solving. Show all your work, as partial credit is awarded generously. Practice with rate problems, related rates, and optimization questions — these appear nearly every year.
Calculator vs Non-Calculator
Know which sections allow calculators and practice accordingly. For calculator sections, master graphing intersections and numerical integration. For non-calculator sections, sharpen your algebraic manipulation and mental math skills.
Study Timeline
Start reviewing core derivative rules 8-10 weeks before the exam. Spend weeks 4-6 on integration techniques. Use the final 3 weeks for full practice exams and reviewing commonly missed concepts.
