The AP Stats exam format
AP Statistics has a revised exam starting in May 2027. It is fully digital, 3 hours long, and a graphing calculator with statistics functions is expected. Formula sheets and tables are provided.
- Section I: 42 multiple-choice questions in 90 minutes, 50%.
- Section II: four free-response questions in 90 minutes, 50%, each scored out of 10. Question 1 focuses on selecting methods and describing data, question 2 on probability, sampling distributions and statistical argument, question 3 is an inference question (a hypothesis test or confidence interval), and question 4 combines several content areas.
The old six-question format with an investigative task is retired, so older practice tests score differently. Use this calculator for the new layout; for an older practice exam, combine its free-response scores into four questions as best you can.
| Section | Scored out of | Weight |
|---|---|---|
| Section I: Multiple choice (42 questions) | 42 questions | 50% |
| Section II: Free response (4 questions, 0–10 each) | 10 + 10 + 10 + 10 pts | 50% |
How this AP Stats score estimate works
Section I: points ÷ 42 × 50 Section II: points ÷ 40 × 50 Composite = sum of the lines above (0–100)
By our estimate a 5 takes about 68 composite points, which an even performance reaches with 29 of 42 multiple-choice questions and 27 of 40 free-response points. A 3 takes about 43: 18 of 42 multiple-choice questions and 17 of 40 free-response points. These lines are educated guesses rather than published cut scores (why), so a result within two or three points of one could go either way.
| AP score | Estimated composite |
|---|---|
| 5 | 68–100 |
| 4 | 55–67 |
| 3 | 43–54 |
| 2 | 32–42 |
| 1 | 0–31 |
Worked example
Noah gets 28 of 42 multiple choice and scores 6, 5, 6 and 4 on the free-response questions (21 of 40).
Multiple choice: 28 ÷ 42 × 50 = 33.3
Free response: 21 ÷ 40 × 50 = 26.3
Composite: 59.6 → estimated 4
Under the new format each free-response point is worth 1.3% of the composite, almost the same as a multiple-choice question (1.2%). Because the free-response scoring is new, cut scores for 2027 are especially uncertain; leave yourself a cushion.
AP Stats scores in 2026
2026 results (the last year of the old format) were spread out: 40% scored 4 or 5, 21% scored a 1, and 62% scored 3 or higher.
Tips for a higher AP Stats score
- Inference has a fixed recipe. State hypotheses and parameter, name the procedure and check conditions, compute, then conclude in context. Each step is typically scored.
- Always answer in context. “Reject H₀” earns little; “there is convincing evidence that the mean wait time is less than 10 minutes” earns the point.
- Describe distributions with all four features. Shape, center, spread and unusual values, in context of the variable.
- Show calculator work in words. Write the test name and inputs (for example, a 2-sample t-test with the sample means and sizes), not just the p-value.
Questions students ask
What changed on the AP Statistics exam?
From May 2027 there are 42 multiple-choice questions and four free-response questions worth 10 points each. The investigative task and the six-question format are gone.
Is a calculator allowed on AP Statistics?
Yes. You are expected to use a graphing calculator with statistical capabilities on both sections.
What score do you need for a 5 in AP Stats?
Our estimate is about 68% of the weighted composite. With a new free-response format, treat any 2027 estimate as rough.
