The AP Statistics Exam From May 2027
This AP Statistics score calculator uses the exam format College Board lists for the course revised for 2026-27: 42 multiple choice questions and four 10-point free-response questions, each section worth half of the score. It returns a composite and an estimated 1 to 5 score.
| Section | Questions | Time | Points | Share of score |
|---|---|---|---|---|
| I: Multiple choice | 42 | 1 hour 30 minutes | 42 | 50% |
| II: Free response | 4 | 1 hour 30 minutes | 40 (10 each) | 50% |
Example. 30 of 42 multiple choice is 71.4%, which adds 35.7. Free-response points of 24 out of 40 are 60%, which adds 30.0. The composite is 65.7%, a 5 in this calculator.
The Four Free-Response Questions
College Board's exam page lists the four questions in this order:
- A multi-part question, mainly on Practices 1 and 2
- A multi-part question, mainly on Practices 3 and 4
- An inference question: a hypothesis test or a confidence interval
- A multi-part question across several content areas, on Practices 2, 3 and 4
Each free-response point is worth 1.25 composite points and each multiple choice question about 1.19, so the two are close in value. The exam is fully digital and taken in the Bluebook app.
Using an Older Practice Exam
Practice exams written before the revision have a different number of questions and a different free-response total. The calculator lets you change the multiple choice count and the free-response maximum for that reason. Take the maximum from the scoring guidelines that come with the practice exam.
The score lines come from the AP Score Conversion Chart in College Board's scoring worksheet for the 2007 AP Statistics Released Exam: a composite of 63 out of 100 for a 5, 49 for a 4, 37 for a 3 and 29 for a 2. As a share of the maximum that is 63%, 49%, 37% and 29%. That exam had 40 multiple choice questions and six free-response questions scored 0 to 4, so its format differs from the revised one. College Board sets new lines for every exam and does not publish them, so the result is an estimate.
The example composite of 65.7% is 2.7 points above the 63% line for a 5. Because the format is new, treat a result near a line as either score. For the statistics behind the course, the Normal Distribution Calculator and the Binomial Probability Calculator work through the calculations.
