Score cutoffs are estimates based on past College Board score reports. Real cutoffs shift 2 to 5 points year to year depending on test difficulty. A score within 3 points of a cutoff could land on either side once official curves are set.
How to Use the AP Stats Score Calculator
AP Statistics Scoring Formula
MC % = (MC correct / 40) × 100 FR % = (Total FR points / 30) × 100 Composite = MC × 0.50 + FR × 0.50 AP Score cutoffs (approximate): 5: 67%, 4: 54%, 3: 42%, 2: 27%
Example: 28/40 MC (70%) and 20/30 FR (67%).
- Composite = (70 × 0.50) + (67 × 0.50) = 68.5%
- Above the 5 cutoff (67%) → AP Score: 5
AP Stats is the most-passed AP exam — pass rate runs around 60% but 5-rates trend slightly higher than other STEM AP exams because the partial-credit-heavy FRQs reward showing work.
AP Stats Pass Rates and FRQ Strategy
AP Statistics is taken by ~190,000 students annually. Pass rate sits at about 60%, with 14-17% earning a 5. The investigative task (Question 6) is heavily weighted at 1/3 of total FR points.
| Score | ~ % of Students | Composite Range |
|---|---|---|
| 5 | ~15% | 67%+ |
| 4 | ~22% | 54-66% |
| 3 | ~23% | 42-53% |
| 2 | ~21% | 27-41% |
| 1 | ~19% | Under 27% |
Three FRQ patterns that show up almost every year:
- Always state your hypothesis with parameters. "H₀: μ = 25, Hₐ: μ > 25 where μ is the true mean." Most students lose 1 point per FRQ to incomplete hypothesis statements.
- Check conditions before running any test. Random sample, normal/Central Limit Theorem condition, independence. The conditions step is worth 1 point on most inference FRQs and is often skipped.
- Investigative Task (Q6) requires explicit reasoning. Worth 10 points (33% of FR). Don't just compute — explain WHY each step. The College Board scorers reward clear reasoning over correct answers.
Frequently Asked Questions
Approximately 67% composite or higher earns a 5 on AP Statistics. That typically means scoring ~28/40 on MC plus ~20/30 on free response. Both sections are weighted 50% in the composite.
