🎯 What is a Good AP Computer Science Principles Score?
A "good" score depends on your goals and target colleges:
- Score of 5: Excellent. Top 12.4% of students. Most selective colleges grant credit.
- Score of 4: Very good. About 34.7% score 4 or 5. Many colleges accept for credit.
- Score of 3: Passing. Demonstrates proficiency in CS principles. Most schools accept for introductory CS credit.
- Score of 2: Below passing. Some schools may grant elective credit.
- Score of 1: No credit, but shows interest in computing that admissions may appreciate.
Important Note: AP CSP is designed as a survey course, not a
programming-intensive class. Many competitive CS programs prefer or require AP CS A instead. However,
CSP still demonstrates valuable computational thinking skills.
What is the Average AP Computer Science Principles Score?
The average (mean) score is approximately 3.08. Key observations:
- AP CSP has one of the highest passing rates among AP exams (~67%)
- The exam is designed to be accessible to students without prior programming experience
- Focus is on computational thinking rather than coding syntax
- The Create Task allows students to demonstrate creativity and problem-solving
📐 Why Are AP Computer Science Principles Scores Curved?
The AP curve ensures consistency across different exam administrations:
- Exam difficulty varies: Some years have trickier MCQs. The curve adjusts so scores remain comparable.
- Equating process: College Board calibrates scores to match performance in equivalent college courses.
- Section weighting: MCQ (70 questions) = 70%, Create Performance Task = 30%.
How We Convert Raw Points
- Multiple-Choice: 70 questions, no penalty for wrong answers. Each correct = 1 point (70 max, worth 70%).
- Create Performance Task: Scored 0-6 on 6 rubric criteria, scaled to 30 points (30% of composite).
- Composite: MCQ Raw + CPT Scaled = 0–100 points, then mapped to 1–5 using cutoff thresholds.
Create Task Scaling: Your CPT raw score (0-6) is multiplied by 5 to give your CPT
composite contribution. Example: 5/6 raw → 25/30 scaled.
🏆 How Do I Get a 5 on AP Computer Science Principles?
Earning a 5 requires approximately 83+ out of 100 points (~83%). Here's a strategic approach:
1. Master the 5 Big Ideas
The exam covers these computational thinking concepts:
🔷 Big Idea 1: Creative Development (CRD)
Collaborative programming, iterative design, documentation
📊 Big Idea 2: Data (DAT)
Binary, data compression, metadata, using data to solve problems
⚙️ Big Idea 3: Algorithms & Programming (AAP)
Variables, control structures, lists, procedures, algorithms
🌐 Big Idea 4: Computing Systems & Networks (CSN)
Internet protocols, fault tolerance, parallel computing
⚖️ Big Idea 5: Impact of Computing (IOC)
Digital divide, bias, privacy, security, legal/ethical issues
2. Create Task Success Strategies
The Create Task is worth 30% of your score. Maximize points with these tips:
- Program Purpose: Clearly state what your program does and why it's useful
- Data Abstraction: Use a list (or similar collection) and explain what it represents
- Manage Complexity: Show how your list simplifies the program vs. using multiple variables
- Procedural Abstraction: Create a student-developed procedure with a parameter
- Algorithm Implementation: Include sequencing, selection (if), AND iteration (loop)
- Testing: Describe two specific test cases with different inputs and results
3. MCQ Strategies
- Practice reading and tracing pseudocode—many questions show code snippets
- Know binary/hex conversions and how data is represented
- Understand internet protocols: TCP/IP, DNS, HTTP, routing
- Be ready for "Impact" questions about ethics, bias, and digital divide
- If stuck, eliminate wrong answers and guess—no penalty!
4. Target Scores
| Target AP Score | MCQ Needed (~) | Create Task Needed |
|---|---|---|
| 5 | 58+/70 | 5-6/6 |
| 4 | 49+/70 | 4-5/6 |
| 3 | 40+/70 | 3+/6 |

❓ Frequently Asked Questions
Is there a guessing penalty on the AP CSP exam?
No. There is no penalty for wrong answers on the multiple-choice section.
Always answer every question. With 4 choices per question, you have a 25% chance on random guesses.
What programming language is used?
AP CSP is language-agnostic for the Create Task—you can use any language
(Python, JavaScript, Scratch, etc.). The MCQ section uses College Board pseudocode, which resembles
simplified programming syntax that's easy to read.
How is the Create Performance Task scored?
The Create Task is scored on 6 rubric criteria (0-1 point each): Program
Purpose/Function, Data Abstraction, Managing Complexity, Procedural Abstraction, Algorithm
Implementation, and Testing. Your raw score (0-6) is scaled to 30 points (30% of your total).
Can I use external libraries or code in my Create Task?
You can use external libraries for functionality, but the algorithm you're
highlighting for the rubric must be student-developed. You cannot claim credit for library-provided
algorithms.
What's the difference between AP CSP and AP CS A?
AP CSP is a broad survey of computer science concepts with lighter
programming emphasis. AP CS A focuses specifically on Java programming with more rigorous coding
requirements. CSP is often taken first and is accessible to beginners.
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.
Do colleges give credit for AP CSP?
Many colleges accept AP CSP scores of 3+ for introductory computing credit.
However, some competitive CS programs may not grant credit or may prefer AP CS A. Always check your
target school's specific policy.
When is the Create Task deadline?
The Create Task is typically due in late April, about 1-2 weeks before the
MCQ exam date. Your teacher will provide the exact deadline. You can only submit once, so
double-check your work against the rubric.
