College Board publishes this exam as Section I: Multiple Choice at 50%, Section II: Question 1 at 12.5%, Section II: Question 2 at 12.5%, Section II: Question 3 (Inference) at 12.5%, Section II: Question 4 at 12.5%.
Where these numbers come from
The composite is exact. College Board publishes what each section of each exam is worth, and this calculator uses those published weights without alteration.
The 1 to 5 is an estimate, and it cannot be anything else. College Board publishes no composite-to-score conversion for any subject. It re-sets those points every year through a standard-setting process tied to the particular group of students who sat that exam, so a fixed table cannot exist. To turn your composite into a score, this tool places it on a normal curve and reads the result against College Board's published 2026 score distribution for your subject. That curve is our assumption, not College Board's. Your real score will not match this exactly.
The distribution is College Board's. Every percentage in the table above is their published 2026 figure.
How the 2027 AP Stats exam is scored
The May 2027 exam is the first one written for the revised course. Section I is 42 multiple-choice questions in 90 minutes. Section II is four free-response questions, each worth 10 points, in another 90 minutes. Each section is half of your composite score.
| Section | What you answer | Time | Weight |
|---|---|---|---|
| Section I: Multiple Choice | 42 questions | 1 hour 30 minutes | 50% |
| Section II: Free Response | 4 questions, 10 points each | 1 hour 30 minutes | 50% |
College Board scores every free-response question (FRQ) on an analytic scale out of 10 and weights the four equally, so each one is 12.5% of the exam. They appear on the exam in this order:
| Question | Points | What it focuses on |
|---|---|---|
| Question 1 | 10 | A multi-part question on Practices 1 and 2: formulating questions and collecting data |
| Question 2 | 10 | A multi-part question on Practices 3 and 4: analyzing data and interpreting results |
| Question 3 | 10 | Inference: a hypothesis test or a confidence interval |
| Question 4 | 10 | A multi-part question on Practices 2, 3, and 4 that draws on multiple content areas |
One multiple-choice question (MCQ) is worth 50 divided by 42, about 1.19 composite points. One free-response point is worth 12.5 divided by 10, exactly 1.25. So a single rubric point counts for slightly more than a single multiple-choice answer. This AP Statistics grade calculator takes your raw points for each free-response question on its own line, the way each one is scored.
A perfect Section I with nothing on Section II lands at exactly 50, and so does the reverse. On this tool’s model, 50 is just inside the 3 band. Neither half alone gets you further.
What changed on the AP Statistics exam for 2027?
College Board revised AP Statistics for the 2026-27 school year to align it with current introductory college statistics courses. Most of the numbers a student might remember from older practice material have changed.
| Through May 2026 | From May 2027 | |
|---|---|---|
| Delivery | Hybrid: Bluebook plus paper free-response booklets | Fully digital: both sections in Bluebook |
| Multiple-choice questions | 40 | 42 |
| Options per multiple-choice question | 5 | 4 |
| Free-response questions | 6 | 4 |
| Points per free-response question | 4 | 10 |
| Course units | 9 | 5 |
| Math prerequisite | Second-year algebra | First-year algebra |
The multiple-choice section now includes two sets of three questions that share a prompt, one on probability and random variables and one on regression. Several topics left the course entirely: the geometric distribution, combining random variables, chi-square goodness-of-fit tests, departures from linearity, and the old Unit 9 on inference for slopes. New topics cover investigative questions, the kind that take a statistical investigation to answer.
On exam day you type your free-response answers instead of writing them in a booklet, and Bluebook’s symbol menu now includes common statistical symbols. You still get scratch paper and a printed reference booklet with the formulas and tables.
The five units and their share of the multiple choice
| Unit | Share of the multiple-choice section |
|---|---|
| 1: Exploring One-Variable Data and Collecting Data | 20% to 30% |
| 2: Probability, Random Variables, and Probability Distributions | 15% to 25% |
| 3: Inference for Categorical Data: Proportions | 15% to 25% |
| 4: Inference for Quantitative Data: Means | 10% to 20% |
| 5: Regression Analysis | 10% to 20% |
Why most AP Stats score calculators are a year behind
We read the input limits of 13 AP Statistics score calculators from US search results. Ten of them still model the old exam: all ten cap multiple choice at 40, and most take free-response scores out of 4. One advertises the 2027 exam while its inputs still follow the old format.
The new rubric does not fit in those boxes. A 7 out of 10 on Question 3 cannot go into a field that stops at 4, and 42 multiple-choice answers do not fit a section built for 40. A calculator built on the old structure either refuses your real scores or leaves you to convert them yourself.
This AP Statistics score calculator uses the 2027 structure instead: 42 multiple-choice questions and four free-response questions, each capped at 10 points.
What percent is a 5 on AP Stats?
Nobody can give you a verified answer for 2027, this page included. College Board does not publish the composite needed for each score, and it sets those cut points separately for each exam. May 2027 is also the first exam in the new format, so there is no history to lean on.
These are the bands this tool models from the 2026 distribution. They match the thresholds the calculator shows under your result.
| AP score | Composite from | What College Board calls it |
|---|---|---|
| 5 | 71.3% | Extremely well qualified |
| 4 | 59.4% | Very well qualified |
| 3 | 49.9% | Qualified |
| 2 | 41.3% | Possibly qualified |
| 1 | below 41.3% | No recommendation |
Is a 70% a 5, then? Not on this model. A 70% composite is a 4, and the 5 starts at 71.3%.
Take a student with 30 of 42 multiple-choice questions right. On this model, 19 of the 40 free-response points would lift them to a 4, and 29 would get them a 5. Half credit on every question, 20 points in all, is enough for the 4.
AP Statistics score distribution 2026
The 2026 results below come from College Board’s AP Statistics score distribution. They are the last from the old format and the most recent it has released.
| AP score | Share of students |
|---|---|
| 5 | 17% |
| 4 | 23% |
| 3 | 22% |
| 2 | 17% |
| 1 | 21% |
Sixty-two percent scored a 3 or higher. The spread is flat: no score reached a quarter of students, the 4 was the most common result at 23%, and more than one in five students scored a 1.
In 2025, the latest year with complete figures, 266,791 students took the exam, the mean score was 2.92, and 60.3% scored a 3 or higher. College Board has not yet published the 2026 count or mean.
What calculator can you use on the AP Stats exam?
A graphing calculator with statistical capabilities, and for 2027 nothing less. College Board’s calculator policy carries an update for this exam: “Nongraphing calculators are not allowed, even those with the required statistics computational capabilities.” That rules out scientific calculators, including ones with statistics functions.
You have two options, and you can use both. Bluebook includes a built-in Desmos graphing calculator on both sections, and you can bring up to two approved handheld graphing calculators. The TI-84 Plus, TI-84 Plus CE, and TI-84 Plus CE Python are all on College Board’s approved list.
Only the Desmos inside Bluebook counts on exam day. The web and app versions of Desmos are fine for practice during the year but cannot be used during the exam.
Is AP Stats hard?
By pass rate, AP Stats is one of the hardest AP exams. In 2026, 62% of students scored a 3 or higher. Of the 40 AP subjects in this site’s calculator, only AP Music Theory (59%) came in lower, and the median subject reached 72%. At the other end, 21% scored a 1. For comparison, AP Calculus AB put 65% at a 3 or higher, with 20% at a 5 and 11% at a 1. Pass rates depend on who takes an exam as well as on the exam itself, which makes them a rough guide to difficulty at best.
The 2027 course drops some topics students used to study, including the geometric distribution and inference for slopes, and it now needs only first-year algebra. The free response changes shape too. Each of the four FRQs now carries 10 points on an analytic rubric instead of the old 4-point scale, so partial credit comes in smaller steps.
When is the 2027 AP Stats exam?
College Board has scheduled AP Statistics for Tuesday, May 11, 2027, as a Session 2 exam. It lasts three hours, split evenly between the two sections, and College Board posts scores to student accounts in July.
How this AP Stats grade calculator estimates your score
The composite is exact. Your multiple-choice total is scaled to 50 points and each free-response question to 12.5, using the weighting College Board publishes for 2027.
The predicted AP score is a model, because College Board does not publish its composite cut scores and resets them for each exam. To estimate one, the tool assumes composites fall on a bell curve and finds where yours sits against the 2026 percentages at each score. The center and width of that curve are this site’s own assumption, not College Board’s.
The 2026 distribution comes from the last old-format exam, and 2027 is the first new one, so nobody yet has real data on how the new exam converts to a 1 to 5. Read a result within a couple of points of a boundary as a range rather than a verdict.
Using an older practice exam
Most released practice material predates the change. For the multiple choice, scale your score to 42: 32 correct out of 40 works out to 33.6 of 42, or about 34. For the free response there is no clean conversion. The old questions used 4-point scoring and the new ones a 10-point analytic rubric, so multiplying an old score by 2.5 gives only a rough reading. For practice that matches the new exam, use the test previews in Bluebook and the practice in AP Classroom.

Frequently asked questions
How many questions are on the AP Stats exam?
Forty-six in total. Section I has 42 multiple-choice questions, and Section II has 4 free-response questions, with 90 minutes and half the score for each.
How many points is each AP Stats free-response question worth?
Ten points, scored on an analytic scale, and the four questions are weighted equally at 12.5% of the exam each. Before 2027, each free-response question was worth 4 points.
Is the AP Stats exam fully digital in 2027?
Yes. Both sections are taken in Bluebook, including the free response, which you type instead of handwriting. You still get scratch paper and a printed reference booklet.
Can I use a TI-84 on the AP Stats exam?
Yes. College Board expects a graphing calculator with statistical capabilities, and the TI-84 Plus, TI-84 Plus CE, and TI-84 Plus CE Python are on its approved list. The Desmos graphing calculator built into Bluebook is also available.
Can I use a scientific calculator on AP Stats in 2027?
No. College Board’s 2027 update says nongraphing calculators are not allowed, even ones with the statistics functions the course needs.
What happened to the Investigative Task?
The 2027 free-response section has four questions: two multi-part questions on the statistical practices, one inference question, and one multi-part question that spans multiple content areas. None of them is an Investigative Task, and the section went from six questions to four.
What is a good AP Stats score?
A 3 is what College Board calls qualified, and 62% of students scored a 3 or higher in 2026. Colleges set their own credit and placement rules, some at a 3 and others at a 4 or a 5, so check the policy of the college you are aiming for.
How accurate is this AP Stats grade calculator?
The composite is exact: it applies the section and question weights College Board lists for 2027. The 1 to 5 is modeled, because no official conversion exists yet for the new exam. A result close to a band edge could fall on either side of it on the day.
