AP Calculus AB — 42 MC + six 9-point FRQs
AP Calc AB Score Calculator
AP Calculus AB is split evenly: 42 multiple-choice questions and six free-response questions worth 9 points each (54 max). Enter practice raw scores to compute a 0–100 composite and an unofficial 1–5 estimate. You cannot take both AB and BC in the same year.

How this AP Calc AB estimate is built
- Add multiple-choice corrects from Part A (no calculator) and Part B (calculator) out of 42 (50%).
- Score each of the six FRQs on a 0–9 rubric and sum them (max 54, 50%).
- Composite = (MC ÷ 42) × 50 + (FRQ ÷ 54) × 50.
- Estimate 1–5 with the unofficial cutoffs in Sources.
FRQ Part A requires a graphing calculator on some problems; Part B does not.
Good for practice
- Scoring a timed practice exam after adding FRQ rubric points
- Comparing calculator vs non-calculator weaknesses inside one MC total
- Setting a target composite before the May administration
- Showing students how expensive a blank FRQ is relative to a few MC misses
Do not treat as an official score
- Entering BC practice totals into an AB calculator
- Using 45 MC as the denominator (that is not AB’s 42)
- Forgetting Part A and Part B both sit inside the single MC count
- Treating an unofficial 5 as permission to skip reviewing FRQ communication points
Worked examples
Comfortable AB practice
30 MC and 40 FRQ points.
4 · ≈ 72.8 / 100
FRQ gap
36 MC but only 24 FRQ points.
65.1 / 100 · ≈ 4
Borderline composite
24 MC and 30 FRQ points.
3 · ≈ 56.3 / 100
Frequently asked questions
How many multiple-choice questions are on AP Calc AB?
42 total: 29 without a calculator and 13 with a calculator, still entered here as one MC total.
Are FRQs really 9 points each?
Yes. Six free-response questions are scored on a 0–9 scale for a 54-point section before weighting.
Can I use this for Calculus BC?
No. BC has a different structure and includes AB subscore rules. Use a BC-specific tool when we publish one.
Why is my school’s curve different?
Teachers often publish classroom curves. This page documents one transparent practice mapping; official scores still come from College Board.
