AP Calculus Score Calculator
Enter your points from a practice exam and I’ll estimate your AP Calculus score from 1 to 5, for AB or BC. It’s an estimate: College Board doesn’t publish current cutoffs, so the scale comes from its released 2012 scoring worksheets.
How the AP Calculus exam is scored
AB and BC have the same format. The exam is hybrid digital: multiple choice in the Bluebook app, written answers by hand in a paper booklet. Each section is half the score.
Multiple choice: 50%
- From May 2027: 42 questions in 1 hour 40 minutes.
- Part A: 29 questions in 62 minutes, no calculator.
- Part B: 13 questions in 38 minutes, graphing calculator.
- Through May 2026 it was 45: 30 in 60 minutes, then 15 in 45 minutes.
- No penalty for a wrong answer.
Written questions: 50%
- 6 questions in 1 hour 30 minutes, each scored out of 9.
- Part A: 2 questions in 30 minutes, graphing calculator.
- Part B: 4 questions in 60 minutes, no calculator.
- You show your work, and the steps earn points, not only the final answer.
On the scoring worksheets College Board released with its 2012 practice exams, the multiple-choice count is multiplied by 1.2, so 45 right is worth 54 points. The six written scores are added as they are, up to another 54. The total, rounded to a whole number, is the composite out of 108. For the 42-question exam, I weight each multiple-choice question 54 ÷ 42, about 1.29 points, so that section is still half. College Board hasn’t released a worksheet for the new format.

AP Calculus score cutoffs (estimated)
College Board doesn’t publish the cutoffs for a current exam: the line is set each year after scoring and not released. The most recent official ones are on the scoring worksheets of its 2012 AP Calculus practice exams, so that’s the scale this calculator uses. Read it as an estimate, because the line can move from year to year.
| AP score | AB composite (out of 108) | BC composite (out of 108) |
|---|---|---|
| 5 | 67–108 | 68–108 |
| 4 | 54–66 | 56–67 |
| 3 | 41–53 | 42–55 |
| 2 | 33–40 | 35–41 |
| 1 | 0–32 | 0–34 |

Common questions
What raw score do you need for a 5 on AP Calc AB?
About 67 out of 108, or 62% of the points, on the scale College Board released with its 2012 AP Calculus AB practice exam. The composite is your multiple-choice points, weighted to 54, plus your six written-question scores out of 9 each. College Board doesn't publish the cutoff for current exams, and it can move from year to year, so 67 is an estimate.
Is a 3 on AP Calculus good?
A 3 is a passing score: College Board calls it qualified. Many colleges give credit or placement for a 3, and others ask for a 4 or a 5. Check each college's AP credit policy before counting on it.
Is AP Calc BC harder than AB?
BC covers everything in AB plus more: series, parametric, polar and vector-valued functions, and a few more integration techniques. So it's more material at a faster pace. The exams have the same format and the same 108-point composite, and the 2012 cutoffs were close: a 5 started at 67 on AB and 68 on BC.
How is the AP Calculus exam scored?
Multiple choice and written questions are each half the score. From May 2027 there are 42 multiple-choice questions (45 before) and 6 written questions, each scored out of 9. There's no penalty for a wrong answer. On College Board's released scoring worksheets, the two halves add up to a composite out of 108, which converts to an AP score from 1 to 5.
1-on-1 AP Calculus tutoring
I’m Michael Seutin, and I tutor AP Calculus AB, one student at a time. When a practice score comes in low, the lost points usually come from a few topics, and often from the algebra and trig underneath the calculus rather than the calculus itself. I find those first. It’s $75/hr online, from anywhere, or $85/hr in person in Solano, Napa and Contra Costa. Month to month. If you’re in BC, ask me.
