📊 2026 Raw Score to AP Score Conversion Chart

Based on College Board data from 2023-2025, here are the estimated composite score ranges for each AP score:

Composite Score (0-80) AP Score Qualification
59 – 80 5 Extremely Well Qualified
46 – 58 4 Well Qualified
35 – 45 3 Qualified
25 – 34 2 Possibly Qualified

How Composite Score is Calculated

Your composite score combines MCQ and FRQ performance:

Composite = MCQ Raw + FRQ Scaled
MCQ: 40 questions = 40 points (50%) | FRQ: 36 raw points scaled to 40 points (50%) | Total: 80 points

📈 AP Computer Science A Score Distributions (2025)

AP Computer Science A has one of the highest 5 rates among AP exams, reflecting the strong preparation of students who choose to take it. The exam attracts students with genuine interest in programming.

5 (27.5%)
4 (23.2%)
3 (20.8%)
2 (11.5%)
1 (17.0%)
AP Score 2025 % 2024 % 2023 %
5 27.5% 26.7% 25.6%
4 23.2% 22.8% 22.1%
3 20.8% 21.3% 20.9%
2 11.5% 11.7% 12.2%
1 17.0% 17.5% 19.2%

Mean Score (2025): 3.32 — This is higher than many AP exams, as students who take CS A typically have strong interest in programming.

🎯 What is a Good AP Computer Science A Score?

A "good" score depends on your goals and target colleges:

  • Score of 5: Excellent. Grants credit for CS1/Intro to Programming at most colleges. About 27.5% of students achieve this—you're in the top tier!
  • Score of 4: Very good. Most colleges award credit. You're in the top 50% of test-takers.
  • Score of 3: Passing. Many schools grant credit, though competitive CS programs may require 4 or 5.
  • Score of 2: Below passing. Some colleges may grant elective credit, but most CS programs do not.
  • Score of 1: No credit, but demonstrates interest in CS that admissions may note positively.
Pro Tip: If you're pursuing a CS major at a top tech school (MIT, Stanford, CMU, etc.), they often don't grant credit even for a 5—they want you to take their intro course. However, a 5 can help with placement into more advanced courses and demonstrates strong preparation.

What is the Average AP Computer Science A Score?

The average (mean) score is approximately 3.32, which is higher than most AP exams. This reflects that AP CS A students:

  • Often have prior programming experience
  • Self-select into the course based on genuine interest
  • Tend to be highly motivated and academically prepared

About 50.7% of students score 4 or 5, making these scores the norm rather than the exception.

📐 Why Are AP Computer Science A Scores Curved?

The AP curve ensures fairness and consistency:

  • Exam difficulty varies: Some years have trickier FRQs. The curve adjusts so a "5" represents consistent mastery.
  • Equating process: College Board calibrates scores to match performance in equivalent college CS courses.
  • Section weighting: MCQ (40 questions) and FRQ (4 questions, 9 pts each) are each worth 50% of the composite.

How We Convert Raw Points

  1. Multiple-Choice: 40 questions, no penalty for wrong answers. Each correct answer = 1 point (40 max).
  2. Free-Response: 4 questions worth 9 points each = 36 raw points, scaled to 40 points (50% of composite).
  3. Composite: MCQ Raw + FRQ Scaled = 0–80 points, then mapped to 1–5 using cutoff thresholds.
FRQ Scaling: Your FRQ raw score (0-36) is multiplied by 40/36 ≈ 1.11 to give your FRQ composite contribution. Example: 27/36 raw → 30/40 scaled.

🏆 How Do I Get a 5 on AP Computer Science A?

Earning a 5 requires approximately 59+ out of 80 points (~74%). Here's a strategic approach:

1. Master the AP Java Subset

Know these classes and methods cold:

  • String: length(), substring(), indexOf(), equals(), compareTo()
  • ArrayList: add(), get(), set(), remove(), size()
  • Math: abs(), pow(), sqrt(), random()
  • Integer: MAX_VALUE, MIN_VALUE

2. Know the FRQ Types

  • FRQ 1 - Methods & Control: Writing methods with loops, conditionals, return statements
  • FRQ 2 - Class Design: Creating a class with instance variables, constructors, methods
  • FRQ 3 - Array/ArrayList: Traversing, modifying, and searching collections
  • FRQ 4 - 2D Array: Nested loops, row/column traversal, manipulating grids

3. FRQ Strategies

  • Write pseudocode first to organize your logic
  • Use meaningful variable names (graders appreciate this)
  • Comment key sections if time permits
  • Check for off-by-one errors in loops
  • Use return statements correctly—they exit the method!

4. MCQ Tips

  • Practice tracing code execution—many questions ask "what is the output?"
  • Watch for common traps: modifying an ArrayList while iterating, integer division, String comparison with ==
  • If stuck, eliminate wrong answers and guess—no penalty!

5. Target Scores

Target AP Score MCQ Needed (~) FRQ Needed (~)
5 32+/40 24+/36
4 26+/40 18+/36
3 20+/40 12+/36

❓ Frequently Asked Questions

Is there a guessing penalty on the AP CS A exam?
No. There is no penalty for wrong answers on the multiple-choice section. Always answer every question, even if you have to guess. You have a 20% chance on each question (5 choices).
What programming language is used?
Java. The exam tests Java programming fundamentals including object-oriented programming, control structures, arrays, ArrayList, and 2D arrays. You should be comfortable with the AP Java Subset of methods and classes.
How many points is each FRQ worth?
Each of the 4 FRQs is scored 0-9, for a total of 36 raw points. This is scaled to 40 composite points (50% of your total score). Partial credit is available, so always attempt every part!
Can I use an IDE or computer during the exam?
No. AP Computer Science A is a paper-based exam. You write code by hand for the FRQs and read/trace code for the MCQs. Practice writing code without an IDE to prepare.
What topics appear most frequently?
The most heavily tested topics are: array/ArrayList traversal and manipulation, String methods, 2D arrays, writing methods with correct return types, and class design. Recursion appears but is a smaller portion of the exam.
How accurate is this score calculator?
This calculator is typically accurate within ±1 AP score point for most students. It uses averaged cutoffs from recent exam years (2023-2025). However, actual cutoffs can shift slightly each year based on overall exam difficulty.
Do colleges give credit for AP Computer Science A?
Most colleges grant credit for scores of 4 or 5, typically for CS1/Intro to Programming courses. However, competitive CS programs (MIT, Stanford, CMU, etc.) often don't grant credit—they want you to take their specific intro course. Always check your target school's policy.
What's the difference between AP CS A and AP CS Principles?
AP CS A focuses on Java programming and is more technical. AP CS Principles is a broader survey of computer science concepts with less emphasis on coding. CS A is typically taken by students interested in CS/engineering majors, while CSP is accessible to a wider audience.
