About the AP® Calculus AB Exam
AP® Calculus AB is an introductory college-level course in calculus. Students cultivate their understanding of differential and integral calculus through engaging with real-world problems represented graphically, numerically, analytically, and verbally. Key topics include limits, derivatives, and integrals, which form the foundation of calculus.
The exam tests your ability to apply these concepts across various contexts. It is divided into a multiple-choice section and a free-response section, each with calculator and no-calculator portions. This score calculator helps you convert your raw scores from each section into a scaled composite score and an estimated final AP score from 1 to 5, providing valuable insight into your exam readiness.
Frequently Asked Questions
Your score is based on a composite score out of 108. The multiple-choice section (45 questions) is worth 54 points (1.2 points per correct answer), and the free-response section (6 questions) is worth 54 points (9 points per question). This composite score is then converted to the final 1-5 AP scale based on a curve determined each year.
Most colleges grant credit for a score of 3, 4, or 5. A score of 4 or 5 will often allow you to place out of an introductory calculus course. However, policies differ widely, so it's essential to check with the specific colleges you're interested in.
Calculus AB covers the equivalent of one semester of college calculus. Calculus BC covers all AB topics plus additional material, equating to a full year of college calculus. BC is faster-paced and includes topics like parametric, polar, and vector functions, and series.
Yes. A graphing calculator is required for Part B of the multiple-choice section (15 questions) and Part A of the free-response section (2 questions). Make sure your calculator is on the College Board's approved list.
This tool uses the official scoring weights and score conversion ranges from previously released College Board data. While it provides a strong estimate, the exact score cutoffs can change slightly each year. Use it as a guide to assess your performance and focus your studies.
No, points are not deducted for incorrect answers on the multiple-choice section. Your score is based only on the number of questions answered correctly. Therefore, it is always best to answer every question, even if you have to guess.
The course is structured around three Big Ideas: (1) Change (using derivatives to describe rates of change), (2) Limits (understanding essential calculus concepts), and (3) Analysis of Functions (using derivatives and integrals to analyze function behavior).
Practice with official past FRQs from the College Board website. Pay close attention to the scoring guidelines to understand how points are awarded. Always show your work, clearly label your answers, and provide justifications when asked (e.g., using the Mean Value Theorem or L'Hôpital's Rule).
The total exam time is 3 hours and 15 minutes. Section I (MCQ) is 1 hour and 45 minutes. Section II (FRQ) is 1 hour and 30 minutes. Each section is split into a calculator and a no-calculator part, so time management is crucial.
Consistent practice is key. Work through problems from your textbook and use official AP Classroom resources. Take full-length, timed practice exams to simulate the test-day experience. Focus on understanding the underlying concepts rather than just memorizing formulas.
