An AP score is not a percent, and College Board does not publish a table that turns one into the other. What College Board does publish is the section weight of every exam, how the parts combine into a composite, how the 1–5 scale is set, and what each score means. This guide uses those published figures for all 14 exams — and labels everything else.
How an AP exam is scored, step by step
1. Multiple choice is scored by computer. There is no deduction for wrong or unanswered questions.
2. Free responses are scored by readers. Teachers and college faculty score them at the AP Reading, against College Board scoring guidelines.
3. The parts are combined into a composite. Each section counts at its published weight. The composite is a weighted score — expressed as a percent of the weighted exam credit, it is the number a calculator can compute honestly.
4. The composite becomes a 1–5 score through score setting. College Board runs standard-setting studies using assembled evidence: AP student performance, the expectations of college faculty, and the grades of college students in comparable courses. The conversion is not published as a percent table.
Colleges then set their own credit and placement policies for AP scores. College Board does not set those either.
Section weights for all 14 exams
| Exam | Multiple choice | Free response | Inside the sections |
|---|---|---|---|
| AP US History | 40% | 40% | SAQ 20% · DBQ 25% · LEQ 15% |
| AP World History: Modern | 40% | 40% | SAQ 20% · DBQ 25% · LEQ 15% |
| AP European History | 40% | 40% | SAQ 20% · DBQ 25% · LEQ 15% |
| AP English Language | 45% | 55% | 3 essays; no per-essay weight published |
| AP English Literature | 45% | 55% | 3 essays; no per-essay weight published |
| AP Psychology | 66.7% | 33.3% | AAQ + EBQ, 7 points each |
| AP Biology | 50% | 50% | 6 FRQs (2 long, 4 short) |
| AP Statistics | 50% | 50% | Revised 2026-27: 42 MCQ, 4 FRQs |
| AP Chemistry | 50% | 50% | FRQ raw points: 3 × 10 + 4 × 4 = 46 |
| AP US Government | 50% | 50% | 4 FRQ types |
| AP Environmental Science | 60% | 40% | 3 FRQs × 10 points |
| AP Human Geography | 50% | 50% | 3 FRQs |
| AP Macroeconomics | 66% | 33% | Long FRQ = 50% of section; sums to 99% |
| AP Microeconomics | 66% | 33% | Long FRQ = 50% of section; sums to 99% |
Weights are College Board's published figures. Macroeconomics and Microeconomics sum to 99% because the published 66% and 33% are rounded from two-thirds and one-third.
What the 1–5 scores mean
| 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.
AP exam score ≠ school course grade
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.
Worked examples
Each example computes a weighted composite percent from practice section scores — the arithmetic our calculators do. None of them outputs a 1–5, because no published conversion exists.
APUSH — 69.2%
- MCQ: 0.40 × 70 = 28.00
- SAQ: 0.20 × 66.67 (6 of 9 points) = 13.33
- DBQ: 0.25 × 71.43 (5 of 7 points) = 17.86
- LEQ: 0.15 × 66.67 (4 of 6 points) = 10.00
Composite = 28.00 + 13.33 + 17.86 + 10.00 = 69.19 ≈ 69.2% of the weighted exam credit.
AP World History — 81.5%
- MCQ: 0.40 × 80 = 32.00
- SAQ: 0.20 × 77.78 (7 of 9 points) = 15.56
- DBQ: 0.25 × 85.71 (6 of 7 points) = 21.43
- LEQ: 0.15 × 83.33 (5 of 6 points) = 12.50
Composite = 32.00 + 15.56 + 21.43 + 12.50 = 81.48 ≈ 81.5% of the weighted exam credit.
AP Chemistry — 69.2%
- MCQ: 0.50 × 66.67 (40 of 60) = 33.33
- FRQ: long 24 of 30 + short 9 of 16 = 33 of 46 points = 71.74% → 0.50 × 71.74 = 35.87
Composite = 33.33 + 35.87 = 69.20 ≈ 69.2% of the weighted exam credit.
AP Environmental Science — 77.0%
- MCQ: 0.60 × 75 (60 of 80) = 45.00
- FRQ: 8 + 8 + 8 = 24 of 30 points = 80% → 0.40 × 80 = 32.00
Composite = 45.00 + 32.00 = 77.0% of the weighted exam credit.
AP Macroeconomics — 67.1%
- MCQ: 0.66 × 66.67 (40 of 60) = 44.00
- FRQ section: 0.50 × 70 + 0.25 × 60 + 0.25 × 80 = 70% → 0.33 × 70 = 23.10
Composite = 44.00 + 23.10 = 67.10 ≈ 67.1% on the published weights. On exact fractions (2/3 and 1/3) the same scores give 67.8% — the gap is purely the rounding of the published weights.
AP Microeconomics — 73.0%
- MCQ: 0.66 × 75 (45 of 60) = 49.50
- FRQ section: 0.50 × 75 + 0.25 × 65 + 0.25 × 70 = 71.25% → 0.33 × 71.25 = 23.51
Composite = 49.50 + 23.51 = 73.01 ≈ 73.0% on the published weights. On exact fractions (2/3 and 1/3) the same scores give 73.8% — the gap is purely the rounding of the published weights.
Assumptions and derived figures
- Equal essay split (assumption). For AP English Language and AP English Literature, College Board publishes only the 55% section weight. Our calculators average the three essay percents equally and label that an assumption.
- Derived per-question weights. Psychology (each FRQ ≈ 16.65%), Chemistry (long 32.61%, short 17.39%), Environmental Science (each FRQ ≈ 13.33%), and Macroeconomics/Microeconomics (long 16.5%, shorts 8.25%) show percents derived from College Board's published raw points and section splits. They are labelled derived wherever they appear.
- FRQ section percent. For Biology, US Government, Human Geography, and Statistics, College Board's exam pages publish no per-question weights, so our calculators take one FRQ section percent instead of inventing point inputs.
- Published-rounded basis. The Macro and Micro calculators use the printed 66% / 33% weights, not exact fractions, and disclose the 99% sum.
Common mistakes
- Believing a cutoff table. Any table that maps composite percents to 1–5 scores is a third-party estimate. College Board publishes none.
- Conflating the exam score with the course grade. They come from different authorities under different rules.
- Using outdated exam formats. Statistics was revised for 2026-27 (42 MCQ, 4 FRQ — not 40 and 6); Psychology has 75 MCQ (not 100); Macro and Micro are 66/33 (not 50/50); the history exams now require all SAQs and a single required long essay.
- Quoting derived figures as published. A percent computed from published points is arithmetic, not a College Board figure, unless College Board prints it.
