How the Calc AB exam is scored
The 2027 AP Calculus AB exam is on Monday, May 10, 2027 (Session 1, usually morning), and AP scores come out in July.[7][8] For May 2027 the AP Calculus exams have 42 multiple-choice questions, and the whole exam takes 3 hours 10 minutes. Calculus is a hybrid exam: multiple choice in Bluebook, free-response answers handwritten in a booklet.[1] In hybrid exams you read everything in Bluebook but handwrite free-response answers in a paper booklet.[4]
| Part | Questions / points | Time | Share of score |
|---|---|---|---|
| Multiple choice, Part A | 29 questions, no calculator | 62 min | 35% |
| Multiple choice, Part B | 13 questions, calculator for some | 38 min | 15% |
| Free response, Part A | 2 questions, calculator required, 9 points each | 30 min | 16.7% |
| Free response, Part B | 4 questions, no calculator, 9 points each | 60 min | 33.3% |
All six free-response questions are scored out of 9, for 54 points, and the two calculator questions come first. In 2025 the averages ranged from 3.26 on question 1 to 4.82 on question 3. Part B, with four no-calculator questions, carries a third of the whole exam.[6][5]

How this Calc AB score estimate works
No Calc AB chart has ever been released, so the 1–5 uses the average of nine other subjects’ charts. See where the cut points come from.

| 2 | 34.6% |
Example
65% of the multiple choice plus the 2025 average free-response scores gives 54.4%: an estimated 3.
Calc AB has one of the widest spreads of results: in 2026, 20% earned a 5 but 24% earned a 2. College Board has never published a conversion chart for the current Calc format, so the cut points here are the average of nine other subjects’ charts. Treat the 1–5 as a rough guide and the weighted percentage as the solid number.
