There's no single percentage that means a 3 or a 4 on every AP exam, because each subject uses its own composite-to-score conversion. But the table below shows the composite percentage behind each score on every subject on this site - and the pattern is useful: on most exams, the mid-40s roughly earns a 3, the high 50s to mid 60s earns a 4, and a 5 lands somewhere in the 60s to mid 70s depending on how hard the exam is.

Left four columns = modeled composite cutoffs used by this site. Right two = approximate recent distribution (share of test-takers). Sort any column by clicking its header.
These are modeled cutoffs for planning, not the official post-exam curve. For your specific subject, the calculator page shows the live model and a downloadable conversion chart, and the score curve guide explains why the official numbers move every year.
How the composite-to-score conversion works
Every AP score starts as raw section scores that get weighted into one composite percentage. On this site the formula is:
Composite % = (MCQ correct ÷ MCQ total × MCQ weight) + (FRQ points ÷ FRQ total × FRQ weight)That composite maps to a final 1-5 through each subject's cutoff curve. The right-hand columns above answer a different question - of everyone who sat the exam, how many landed in each band - which is a measure of cohort performance, not of your personal chances. You can see the exact formula applied with live numbers on any subject calculator.
AP score percentages FAQ
What percentage is a 5 on an AP test?
Two different numbers get confused here. The composite percentage you need for a 5 (the cutoff, ~60-70% on most subjects) is set by the curve each year. The share of students who actually get a 5 (the 5-rate) is a separate stat - it averages about 18% across subjects but ranges from about 8% (AP Physics 1) to about 50% (AP Chinese/Japanese).
Do I need 70% to get a 5 on every AP exam?
No. Every subject uses its own composite-to-score conversion, which is exactly why the table above lists a different percentage for every exam. On generous curves a 5 can start in the low 60s; on strict curves it can require the mid 70s.
What composite percentage is a passing score?
A 3 - the passing line - typically starts around the mid-40s composite on most subjects, though the exact cutoff varies by exam. See the per-subject table for your course.
Why does the percentage for a 3 or 5 change every year?
Because the College Board sets cutoffs by statistical equating after each exam, comparing difficulty against prior years. The curve guide explains how that works.
How to read the table
- Left four columns = this site’s modeled composite cutoffs — the percentage of the composite you need for each score. These are the planning numbers.
- Right two columns = the share of real test-takers who earned a 5, and the pass rate (3+). These are cohort statistics, not cutoffs.
- Compare down a column to see which subjects are friendlier — a lower % for a 5 usually means a harder exam with a more generous conversion.
- Sort any column by clicking its header to line subjects up the way you care about.
The two halves answer different questions: “what do I need to score?” (cutoffs) vs. “how do other students actually do?” (distribution). Keep them separate when you plan.
