How AP Exam Score Curves Work
AP scores are calculated by converting raw section scores into a combined composite total using official College Board section weights. That composite total is mapped against cut scores to determine your final 1–5 grade.
Target Composite Scores by Subject
| AP Exam | Multiple Choice Weight | FRQ Weight | Min Composite for a 5 |
|---|---|---|---|
| AP Psychology | 67% | 33% | ~75% |
| AP Biology | 50% | 50% | ~77% |
| AP Chemistry | 50% | 50% | ~61%* |
| AP Physics 1 | 50% | 50% | ~68%* |
| AP Environmental Science | 60% | 40% | ~85%* |
| AP US History | 40% | 60% | ~64% |
| AP World History | 40% | 60% | ~73%* |
| AP US Gov & Politics | 50% | 50% | ~69%* |
| AP Human Geography | 50% | 50% | ~75%* |
| AP Macroeconomics | 66% | 34% | ~70%* |
| AP Microeconomics | 66% | 34% | ~70%* |
| AP Calculus AB | 50% | 50% | ~63% |
| AP Computer Science A | 55% | 45% | ~70%* |
| AP English Lang | 45% | 55% | ~68% |
| AP English Lit | 45% | 55% | ~70%* |
| AP Statistics (2026-27) | 50% | 50% | unknown** |
*Rougher estimate than AP Psychology/Biology/APUSH/Calc AB/Lang — no official College Board cutoff table exists for these subjects; modeled from pass-rate/mean-score data where available. **AP Statistics format changes for 2026-27 with no released scoring data yet; see warning shown in the calculator above. AP Physics 1 uses the current (pre-2027) format — a further format change is expected for the May 2027 exam.
Frequently Asked Questions
AP scores are calculated by multiplying raw correct answers from multiple-choice questions and free-response rubric scores by section-specific weights. The weighted totals sum into a final composite score evaluated against predefined cutoff boundaries.
No, there is no penalty for guessing on AP exams. Points are awarded solely for correct responses, so leaving answers blank is discouraged.
A score of 3 or higher is generally considered passing and eligible for college credit, though selective universities frequently require a 4 or 5.
Confidence varies by subject:
• Highest confidence (structure and cutoffs modeled off multiple years of released data): AP Psychology, Biology, US History, Calculus AB, English Language.
• Confirmed structure, rougher cutoff estimate (no official cutoff table exists for these subjects at all — estimates draw on reported pass rates/mean scores where available): AP Chemistry, US Gov & Politics, World History, Human Geography, Environmental Science, English Literature, Computer Science A.
• Structure partly unconfirmed: AP Macroeconomics and Microeconomics — section weights (66%/34%) are confirmed via AP Central, but the exact raw point values for each individual FRQ are not published there and are an assumption (10/5/5 pts) based on the exam's typical structure.
• In transition: AP Physics 1 uses its current (pre-2027) format; College Board has confirmed a redesign (fewer MCQs, different FRQ points) effective the May 2027 exam that isn't reflected here yet. AP Statistics uses the upcoming 2026-27 redesigned format, for which no scoring data exists yet at all — see the in-app warning when that subject is selected.
