How AP Exams Are Scored — Complete Guide (2026)
AP exam scoring can seem mysterious — you finish the exam, wait months, and get a single number between 1 and 5. Here's exactly how that number is calculated.
The Two-Part Structure
Every AP exam has two sections:
- Multiple Choice (MC) — machine-graded, typically 40–60% of your score
- Free Response (FRQ) — human-graded, typically 40–60% of your score
Each section is scored separately, then combined into a composite score.
Step 1: Raw Scores
Your raw score is simply the number of points you earn:
- MC: 1 point per correct answer. No penalty for wrong answers (since 2011).
- FRQ: Each question has a point value. Graders award partial credit.
Step 2: Weighted Composite Score
The raw scores from each section are scaled and combined using weights set by College Board.
Example — AP Biology:
- MC: 60 questions × 1pt = 60 raw points → scaled to 50% of composite
- FRQ: 6 questions × 10pts = 60 raw points → scaled to 50% of composite
- Composite max: 150 points
The formula looks like this:
Composite = (MC raw / MC max) × MC weight × Composite max
+ (FRQ raw / FRQ max) × FRQ weight × Composite max
Step 3: Score Cutoffs
College Board sets cutoff points each year that determine which composite score earns a 1, 2, 3, 4, or 5. These cutoffs are set after the exam based on that year's performance.
AP Biology example cutoffs:
| Score | Composite needed |
|---|---|
| 5 | 110–150 |
| 4 | 85–109 |
| 3 | 65–84 |
| 2 | 50–64 |
| 1 | 0–49 |
Why the Cutoffs Change Each Year
College Board uses a process called equating to ensure consistent standards across years. If one year's exam was harder, the cutoffs are adjusted downward so a 3 this year represents the same knowledge as a 3 last year.
This is why you can't predict your exact score until results are released — the final cutoffs depend on how all students performed.
How to Use This to Your Advantage
Knowing the scoring structure helps you study smarter:
- Target the composite you need — use our calculators to find the exact raw scores required for a 4 or 5
- Prioritize MC — each correct answer is worth the same, so consistency matters
- Don't skip FRQ questions — partial credit means even incomplete answers earn points
- Know your exam's structure — some exams weight FRQ higher (like AP English at 55%)
