AP Statistics score calculator
On the AP Statistics exam, the 42 multiple-choice questions are 50% of your score and the free response, four questions worth 10 points each, the other 50%, so one free-response point counts as much as about 1.1 multiple-choice answers. Enter your practice marks for your score out of 100 on those weights. The College Board publishes no chart that turns it into a 1 to 5, so this page does not guess one.
Example: weighted AP Stats score
33.3 from multiple choice (28 of 42) + 30 from free response (24 of 40), by the College Board’s weights: 50% and 50%.
One more multiple-choice answer adds 1.19 and one more free-response point 1.25: a free-response point is worth as much as 1.1 multiple-choice answers.
To reach 70 of 100: 30 of the 40 free-response points with your 28 multiple-choice answers (6 more than now), or 34 of the 42 multiple-choice answers with your free response as it is (6 more).
- Multiple choice, 28 right33.3 of 50

The College Board publishes no chart that turns this into a 1 to 5 for today’s exam, so this is not your AP score.

How the weighted score is worked out
- The exam: 42 multiple-choice questions (single questions and sets on a shared prompt, four answer choices each, in 1 hour 30 minutes), then 4 free-response questions in 1 hour 30 minutes.
- Multiple choice: your answers right ÷ 42 × 50. Each answer is worth 1.19.
- Free response: add your question scores (out of 40), then ÷ 40 × 50. Each point is worth 1.25.
- Add the two: a score out of 100 with the sections in the College Board’s proportions, 50% and 50%.
The College Board does not say how it combines the sections into the composite behind your AP score, only what share each section has, so this is the plainest reading of those shares.
The exam changes in May 2027: 42 multiple-choice questions with four answer choices each (before, 40 with five) and four free-response questions of 10 points (before, six of 4 points). The exams up to May 2026, and practice exams taken from them, have the earlier format, so this page does not fit them.
A worked example
28 of 42 multiple-choice answers right: 28 ÷ 42 × 50 = 33.3. Free-response scores of 7, 6, 5 and 6 make 24 of 40: 24 ÷ 40 × 50 = 30. Together 63.3 of 100.
Where the next points are: a multiple-choice answer adds 1.19 and a free-response point 1.25, so one free-response point counts as much as about 1.1 multiple-choice answers.
What each free-response question is worth
Each question’s points are from the College Board’s course and exam description for the exam from May 2027 (four 10-point questions, 12.5% of the score each), whose sample questions come with scoring guidelines on that scale.
| Question | What it asks | Points | Of your 100 | As many multiple-choice answers as |
|---|---|---|---|---|
| Question 1 | Formulate a question and collect data | 10 | 12.5 | 10.5 |
| Question 2 | Analyze data and interpret the results | 10 | 12.5 | 10.5 |
| Question 3 | Inference: a hypothesis test or a confidence interval | 10 | 12.5 | 10.5 |
| Question 4 | Collect, analyze and interpret data across the course | 10 | 12.5 | 10.5 |
To practice, AP Central posts the last three years’ AP Stats free-response questions with their scoring guidelines and sample answers from students who sat the exam: past AP Stats exam questions. Those are in the format up to May 2026, six questions scored out of 4, so they do not fit these weights.
Why there is no 1 to 5 here
The College Board sets the composite each AP score needs after every exam and publishes no chart for today’s AP Stats exam. A 1 to 5 from any calculator is someone’s guess at those cut points.
What it does publish is how students scored. In 2026, on the exam in its earlier format: 17% a 5, 23% a 4, 22% a 3, 17% a 2 and 21% a 1; 62% scored a 3 or higher. Those are shares of students, not the marks each score needed.
