How the AP Statistics exam is scored
| Section | Questions | Time | Weight |
|---|---|---|---|
| Multiple Choice (Section I) | 42 questions | 1 hr 30 min | 50% |
| Free Response (Section II) | 4 questions | 1 hr 30 min | 50% |
This is the revised exam for the 2026-27 school year, fully digital in Bluebook. College Board does not publish per-question FRQ weights, so this calculator takes your FRQ section percent as a whole.
Worked example
- MCQ: 0.50 × 71.43 (30 of 42) = 35.71
- Free response: 0.50 × 75 = 37.50
Composite = 35.71 + 37.50 = 73.21 ≈ 73.2% of the weighted exam credit.
What the composite percent is — and is not
College Board does not publish a fixed percent-to-AP-score conversion, for AP Statistics or any other AP exam. Scores are set through score-setting studies — weighing AP student performance, the expectations of college faculty, and the grades of college students in comparable courses — and the conversion is not printed as a table. Any site that prints cutoffs like “75% = a 5” is estimating. This calculator does not use such a table, and its result is not a predicted AP score.
| AP score | College Board wording | College course grade equivalent |
|---|---|---|
| 5 | Extremely well qualified | A+ or A |
| 4 | Very well qualified | A−, B+, or B |
| 3 | Qualified | B−, C+, or C |
| 2 | Possibly qualified | — |
| 1 | No recommendation | — |
One wording variant: the score-setting table above calls a 4 “Very well qualified.” Some College Board pages shorten it to “well qualified.” The meaning is the same.
Your AP exam score and your school course grade are different things. The 1–5 score comes from College Board for the exam alone. Your course grade is set by your teacher and school under their own policy — homework, tests, participation, and weighting. The “college course grade equivalent” column is the college grade College Board benchmarks each score against in its standard-setting; it is not a rule that your teacher must award that grade in your class.
Assumptions on this page
- Revised format. This calculator uses the 2026-27 structure College Board publishes now: 42 MCQ and 4 FRQ. The old 40-question, 6-FRQ format is outdated and is not used.
- FRQ entered as one section percent. No per-question weights are published.
- The result is a weighted composite percent — an estimate of exam credit earned, not an AP score.
Common mistakes
- Treating the composite as a 1–5 score. No published conversion exists; 73.2% is not “a 4.”
- Using the old format. Guides describing 40 MCQ and 6 FRQs (including an investigative task) describe the pre-2026-27 exam.
- Carrying old sub-weights forward. The old format’s per-question weights do not apply to the revised exam.
