How is the AP Calculus exam scored?

AP Calculus has two sections, each worth 50% of the composite score. Section I: 45 MCQ (each correct = 1.2 composite points, max 54). Section II: 6 FRQs worth 9 points each (1.0 composite point each, max 54). Total composite maximum is 108. This is scaled to a 0–100 equivalent before setting 1-5 grade cutoffs. A score of ~69+/108 typically earns a 5 on AP Calc AB.

What is a passing score on AP Calculus AB?

A score of 3 (qualified) on AP Calculus AB typically requires approximately 40 composite points out of 108 — roughly 37% of total points. This translates to about 18/45 correct on MCQ and ~22/54 on FRQ combined. About 60% of AB students score 3 or higher. A 4 requires approximately 52 composite points; a 5 requires approximately 69.

Is AP Calculus BC harder to score a 5 on than AB?

BC requires slightly more composite points for a 5 (72 vs. 69) but has a much higher rate of 5s (38-43% vs. 18-22%). This is because AP Calculus BC self-selects a stronger student population — students who take BC are typically among the strongest math students. In absolute terms, BC material is more advanced (series, parametric equations, polar coordinates), but the exam is calibrated to the BC population.

What calculators are allowed on AP Calculus?

Any College Board-approved graphing calculator. Commonly used: TI-84 Plus, TI-84 Plus CE, TI-Nspire CX, Casio fx-9750GIII. Calculators with CAS (computer algebra system) that can do symbolic math are NOT allowed (TI-Nspire CAS is banned). Calculators can only be used during designated calculator sections: MCQ Part B (15 questions) and FRQ Part A (2 questions).

AP Calculus Exam Structure (AB and BC)

Both AP Calculus AB and AP Calculus BC follow the same structure:

Section I — Multiple Choice: 45 questions, 105 minutes - Part A: 30 questions, no calculator, 60 minutes - Part B: 15 questions, graphing calculator allowed, 45 minutes - Worth: 50% of composite score

Section II — Free Response: 6 questions, 90 minutes - Part A: 2 questions, graphing calculator allowed, 30 minutes - Part B: 4 questions, no calculator, 60 minutes - Worth: 50% of composite score

Scoring Calculation

Section I (MCQ): 45 points possible (1 point per question) Section II (FRQ): 54 points possible (9 points per question × 6 questions)

Composite conversion:

Section I composite contribution = (MCQ raw / 45) × 54

OR using the standard weighting: - Section I (45 MCQ): Each correct = 1.2 composite points → 54 points max - Section II (6 FRQ × 9 pts): Each point = 1.0 composite point → 54 points max

Total composite maximum: 108 points (before scaling)

The 108-point raw composite is scaled to a 0–100 equivalent for grade cutoff setting.

Worked Example: AP Calculus AB

Student scores: - MCQ: 34 correct out of 45 - FRQ: 32 points out of 54 total

Section I contribution: 34 × 1.2 = 40.8 composite points Section II contribution: 32 × 1.0 = 32.0 composite points

Total composite: 72.8 out of 108

As percentage: 72.8 / 108 × 100 = 67.4%

Composite to AP Score Conversion (Approximate)

AP Calculus AB: | Composite Points | AP Score | |-----------------|---------| | 69–108 | 5 | | 52–68 | 4 | | 40–51 | 3 | | 28–39 | 2 | | 0–27 | 1 |

AP Calculus BC: | Composite Points | AP Score | |-----------------|---------| | 72–108 | 5 | | 57–71 | 4 | | 42–56 | 3 | | 29–41 | 2 | | 0–28 | 1 |

The 72.8 example → AP Calculus AB: 5 (above the ~69 composite threshold)

AP Calculus BC Subscore: AB

AP Calculus BC students also receive an AB subscore representing their performance only on AB-topic questions. This subscore ranges 1–5 and can be used for credit at schools that only accept AB credit.

Score Distributions

AP Score	Calc AB %	Calc BC %
5	18–22%	38–43%
4	17–20%	17–20%
3	20–22%	14–17%
2	20–23%	11–14%
1	19–22%	11–14%

BC pass rate (3+) is much higher because BC attracts students who are already strong in math. AB attracts a broader population.

FRQ Point Structure

Each FRQ is worth 9 points total, typically broken into 3–5 sub-parts: - Limit and continuity: 2 points - Derivatives (chain rule, implicit): 3 points - Integral calculation: 2 points - Interpretation/justification: 2 points

Key FRQ strategy: Show all work. Correct setup earns partial credit even if arithmetic errors lead to wrong final answers. Write justification sentences for all conclusions about increasing/decreasing, concavity, or extrema.
