What the exam looks like
The AP Calculus AB exam takes 3 hours and 15 minutes and has two sections.
| Section | Part | Questions | Time | Calculator |
|---|---|---|---|---|
| I: Multiple choice | A | 30 | 60 min | Not allowed |
| I: Multiple choice | B | 15 | 45 min | Graphing calculator required |
| II: Free response | A | 2 | 30 min | Graphing calculator required |
| II: Free response | B | 4 | 60 min | Not allowed |
Each free-response question is scored out of 9 points, for 54 raw points in total.
The math behind your composite score
Here is the calculation the calculator runs for you:
- MCQ points = number correct × 1.2 (maximum 54)
- FRQ points = the sum of your six question scores (maximum 54)
- Composite = MCQ points + FRQ points (maximum 108)
There is no penalty for wrong answers, so leaving a multiple-choice question blank never helps you.
Two examples
Student A answers 32 multiple-choice questions correctly and earns 30 FRQ points.
MCQ: 32 × 1.2 = 38.4. Composite: 38.4 + 30 = 68.4, which rounds to 68. That lands in the 4 range.
Student B answers 25 multiple-choice questions correctly and earns 20 FRQ points.
MCQ: 25 × 1.2 = 30. Composite: 30 + 20 = 50. That is a 3.
Notice what the numbers show. Student A is only a couple of points from a 5, and a single extra FRQ part or a few extra MCQs could close that gap.
Estimated composite ranges
The College Board does not publish an official raw-to-score table for this exam. It sets the cutoffs after each administration, based on how hard that year’s paper was. Past exams suggest ranges close to these:
| Composite (out of 108) | Predicted AP score |
|---|---|
| About 70–108 | 5 |
| About 55–69 | 4 |
| About 42–54 | 3 |
| About 30–41 | 2 |
| 0–29 | 1 |
Treat these as estimates. In a hard year the real cutoffs can sit a few points lower, and in an easy year a few points higher. If your result lands near a boundary, assume it could go either way.
What you need for a 5
If you reach about 70, you are in the 5 range. Some combinations:
- 30 FRQ points: you need about 34 multiple-choice questions correct.
- 36 FRQ points: you need about 29 multiple-choice questions correct.
- 40 FRQ points: you need about 25 multiple-choice questions correct.
You can make up for a weaker section with a stronger one, but FRQ points are harder to earn because partial credit depends on showing correct work.
How students actually scored
The College Board’s published distribution for the 2026 exam:
| AP score | % of students |
|---|---|
| 5 | 20% |
| 4 | 28% |
| 3 | 17% |
| 2 | 24% |
| 1 | 11% |
About 65% of students earned a 3 or higher. For comparison, the 2025 exam had 20.3% 5s and a mean score of 3.21. The distribution is uneven, with many students at the top and a large group at 2, which reflects how differently prepared test takers are for this exam.
Where students lose points
Calculator discipline. Part A of the FRQ and Part B of the MCQ allow a graphing calculator, and the other parts do not. Practise both modes. Know how to find a numerical derivative, an integral, and an intersection, and write the setup before the answer.
Justification. FRQs ask you to justify conclusions, not just state them. If you say a function has a maximum, show the sign change in the derivative or cite the test you used. A correct answer without justification often earns only part of the credit.
Units and context. Rate and accumulation problems usually need units in the answer and a sentence connecting the number to the situation.
Skipped parts. Each FRQ has several parts, and each part is scored separately. Attempt every part, even when you cannot finish the question.
College credit
A 3 is the usual passing score, but credit policies vary. Many colleges grant calculus credit or placement for a 4 or 5, and some accept a 3. Selective schools, and engineering and science programs especially, often set the bar at 4 or 5. Check each college’s AP credit policy page before settling on a target.
How to use this calculator
- Enter the number of multiple-choice questions you answered correctly (0–45).
- Enter your score for each free-response question (0–9 each).
- Read your composite out of 108 and your predicted AP score.
When scoring practice FRQs, use the official rubrics and be strict about the justification and the setup lines. Self-scoring tends to run generous.
Quick answers
Is the AP Calculus AB exam curved?
The College Board equates each exam so that scores keep the same meaning from year to year. This is why cutoffs move by a few points.
How many points is each multiple-choice question worth?
1.2 points on the composite, because the 45 questions are scaled to 54.
Do wrong answers lose points?
No. Answer every question.
What is a good score?
A 4 or 5 is strong. A 3 is generally considered passing.
Is this calculator official?
No. It is an unofficial estimator built on past scoring patterns, and your real result depends on the curve for your exam year.
