How AP Calculus AB Scoring Works

The AP Calculus AB exam is 3 hours and 15 minutes. It's a hybrid exam — MCQs on Bluebook, FRQs handwritten. Both sections have calculator and no-calculator parts.

SectionPartQuestionsTimeCalculatorWeight
I (MCQ)A30 questions60 min❌ No50%
I (MCQ)B15 questions45 min✅ Required
II (FRQ)A2 questions30 min✅ Required50%

Composite: MCQ raw (0-45) × 1.2 = scaled (max 54) + FRQ raw (6 × 9 = max 54) = 108 total.

How to Score a 5 on AP Calculus AB

📝 MCQ Strategy (50%)

45 questions across 2 parts. Part A (no calc) = 30 questions in 60 min (~2 min each). Part B (calc) = 15 in 45 min (~3 min each).

Key: On Part A, master derivative shortcuts mentally. On Part B, use your calculator for definite integrals and equation solving.

✏️ FRQ Strategy (50%)

6 questions × 9 pts = 54 pts. Each FRQ has 4 parts scored independently. Show all work — partial credit is huge.

Key: Always justify with theorems (IVT, MVT, EVT) when prompted. Label graphs. Include units in contextual answers.

🔢 Calculator Tips

Calculator allowed on MCQ Part B and FRQ Q1-Q2. Know these 4 operations cold: graph, solve equations, evaluate derivatives, compute definite integrals.

Key: You must show the setup (equation/integral) even when using calculator. Just writing "calculator says 4.23" earns 0.

📊 FRQ Patterns

Common types repeat yearly: rate/accumulation (Q1), area/volume (Q2), graph analysis (Q3), table/Riemann (Q4), diff eq (Q5), mixed (Q6).

Key: Practice past FRQs from AP Central. The contexts change but the calculus patterns stay the same.

Frequently Asked Questions

45 MCQs (50%) + 6 FRQs worth 9 points each (50%). MCQ raw × 1.2 = max 54 scaled. FRQ max = 54. Composite max: 108. Both sections split into calculator and no-calculator parts.
Yes! During the 60-minute Part B (no calculator), you can continue working on Part A problems — but without your calculator. Plan accordingly.
Rate/accumulation, area/volume, graph-based analysis, table/Riemann sums, differential equations, and mixed derivative/integral problems. These patterns repeat yearly with different contexts.
Yes — unlike AP Chemistry, there is NO formula sheet provided. You must memorize derivative rules, integral formulas, and key theorems (IVT, MVT, FTC).
A graphing calculator (TI-84, TI-Nspire, etc.) is required. Know 4 key operations: graphing, solving equations, numerical derivatives, and definite integrals. Practice these before exam day.
If you're comfortable with precalculus and plan to study STEM, BC covers more material and can earn you more college credits. AB is better if you want a solid foundation without the extra pace. BC includes an AB subscore, so you get two scores.
The score distribution has a "valley" at 3 (15%) with more students at 2 (22.8%) and 4 (28.9%). This bimodal pattern suggests students either grasp calculus concepts well or struggle significantly — there's less middle ground.
Scheduled for May 2026. Hybrid format: MCQs on Bluebook (digital), FRQs handwritten. Total: 3 hours 15 minutes.
