"AP Statistics Score Calculator" is searched after every practice exam and in the week after the real one, by students who want to turn a raw score into the 1 to 5. The arithmetic is published by the College Board and is on this page with a calculator; the only unknown is where the cut points fall, which the College Board sets after each exam and does not publish, so every calculator, this one included, uses estimates from released curves and says so. This page has the May 2027 format (which changed from the 2026 exam), the calculator, the estimated conversion table with raw-score examples, the May 2025 results, the free-response point values from the scoring guidelines, where the points are lost, and a printable worksheet.
Download the AP Statistics score worksheet and conversion table (PDF) (the May 2027 format, the worksheet, the estimated conversion table with raw-score examples, the 2025 distribution, where the points are lost and a plan by practice score; two pages, free).
How the exam is scored
| Section | Questions | Time | Share of the score | Points |
|---|---|---|---|---|
| I: multiple choice | 42 | 1 hour 30 minutes | 50% | 42, one each; no penalty for wrong answers |
| II: free response | 4 | 1 hour 30 minutes | 50% | 40: Question 1: multi-focus (practices 1 and 2) 10; Question 2: multi-focus (practices 3 and 4) 10; Question 3: inference (test or interval) 10; Question 4: multi-focus (practices 2, 3 and 4) 10 |
| Total | 3 hours | 100% | composite as a percentage |
Section I. Individual questions and sets on a shared prompt, across all five units and the four statistical practices; a graphing calculator with statistics functions is expected.
Section II. Four 10-point questions, 40 in all, in the revised exam the College Board describes for the 2026-27 school year. The sections are weighted equally at 50 percent.
The composite. The College Board converts each section to its share of the score (50 percent for the multiple choice, 50 for the free response) and adds them; the composite is then converted to a 1 to 5 with cut points set after the exam so that the standard stays constant from year to year. The exam is fully digital in the Bluebook app, 3 hours in total, on Tuesday 11 May 2027.
What changed for 2027. Through May 2026 the exam had 40 multiple-choice questions and six free-response questions scored 0 to 4 each (five focused questions and an investigative task), with the free-response parts graded E, P or I. From May 2027 it is 42 multiple-choice questions and four 10-point free-response questions. Released papers from 2026 and before are still good practice for the content; score them with the 2027 weights by converting each section to a percentage.
The calculator
Enter the multiple choice correct and the points on each free-response question from a practice paper marked to the scoring guidelines (be strict: a reader is).
AP Statistics score calculator (May 2027 format; estimated cut points)
Composite = 50% x (multiple choice correct / 42) + 50% x (free-response points / 40). The 1 to 5 is read from estimated cut points (70%, 57%, 44% and 32% of the composite for a 5, 4, 3 and 2), which are estimates from released curves; the College Board sets the real cut points after each exam and does not publish them. A composite within three points of a cut is on the line. No penalty for wrong multiple-choice answers.
The conversion table (estimates)
| AP score | Composite (estimate) | For example | What it means |
|---|---|---|---|
| 5 | 70% and up | 29 of 42 multiple choice and 28 of 40 free response | Extremely well qualified |
| 4 | 57% to 69% | 24 of 42 multiple choice and 23 of 40 free response | Well qualified |
| 3 | 44% to 56% | 18 of 42 multiple choice and 18 of 40 free response | Qualified |
| 2 | 32% to 43% | 13 of 42 multiple choice and 13 of 40 free response | Possibly qualified |
| 1 | under 32% | No recommendation |
The raw-score examples assume the same percentage in both sections; any mix that gives the composite works. These cut points are estimates from the released curves of past years. The College Board sets them after each administration and they move by a few points; a practice composite within three points of a boundary is on it, not over it.
A worked example. 31 of 42 multiple choice right and free-response scores of 7, 7, 7, 7 (28 of 40): composite 71.9 percent, which is a 5 on the table, with little margin: a composite within three points of a cut is on the line, and one more free-response point on two questions is the safe side.
The May 2025 results
| Score | 5 | 4 | 3 | 2 | 1 | 3 or higher | Mean |
|---|---|---|---|---|---|---|---|
| Share of 266,791 students | 17.0% | 21.4% | 21.9% | 15.9% | 23.7% | 60.3% | 2.92 |
From the College Board's student score distributions for the May 2025 exams. The share at each score is the real guide to the cut points: a 5 in Statistics is the top 17.0 percent of the students who sat it, whatever the raw score that took.
What the free-response questions ask
- Question 1 (practices 1 and 2): describe a distribution or a study design and select the right method, with the reasoning for the choice
- Question 2 (practices 3 and 4): carry out a calculation or a probability and argue from the result in context
- Question 3: a full inference procedure, a hypothesis test or a confidence interval, with the conditions checked, the computation and the conclusion in context
- Question 4 (practices 2, 3 and 4): a multi-part question across content areas, usually with data to analyse and a decision to justify
Where the points are lost
- Conditions for inference not checked, or checked without reference to the data (random sample, 10 percent, normality or large counts)
- The conclusion of a test stated as 'reject' or 'fail to reject' with no context and no link to the p-value
- Statistical words used loosely: 'correlation' for any association, 'proves' for 'provides evidence', 'accept the null'
- A probability or a value read from the calculator with no statement of what was computed (the distribution, the parameters)
- The experimental design questions answered without the three principles (control, randomisation, replication) applied to the actual study
From a practice composite to the exam
| Practice composite | Likely score now | What moves it most |
|---|---|---|
| under 44% | 1 or 2 | content first: the units with the most multiple-choice misses, then one free-response question a week marked to the scoring guidelines |
| 44% to 56% | 3 | the free response: every lost point is a specific missing thing on the rubric; fix the pattern, not the question |
| 57% to 69% | 4 | timing and the hardest question type; a full timed paper every two weeks |
| 70% and up | 5 | keep it: a timed paper every two weeks and the free-response questions that score under 70 percent |
