AP Score Distributions 2026 — Complete Data for All Exams
By Sarah Mitchell · March 22, 2026 · 3 min read · ✓ Verified 2026 CB data
Understanding score distributions helps you set realistic targets. If 22% of students score a 5 on AP Psychology but only 11% do on AP US History, those are very different challenges. Here's the complete distribution data for all major AP exams.
What Is a Score Distribution?
College Board publishes the percentage of students who earn each score (1–5) for every AP exam each year. This data tells you:
How competitive a given score is
Whether an exam is easier or harder relative to others
AP Chinese Language — 47% (many heritage speakers take the exam)
AP Calculus BC — 39% (self-selected, advanced students)
AP Physics C: Mechanics — 35%
AP Physics C: E&M — 30%
AP Spanish Language — 24%
AP Computer Science A — 26%
AP Psychology — 22%
AP Calculus AB — 22%
Which AP Exams Have the Lowest 5 Rate?
AP Environmental Science — 8%
AP English Literature — 8%
AP Human Geography — 11%
AP US History — 11%
Note: A low 5-rate doesn't always mean an exam is harder — it can reflect the student population taking it. AP Environmental Science has a lower 5-rate partly because more students with varying preparation levels take it.
