Understanding how the exam is scored helps you prepare strategically and use our calculator effectively. For general information about how AP exams are scored, visit our AP Score Calculators page.

Exam Structure Overview

The AP Physics C: Mechanics exam consists of two main sections, each contributing equally to your final score. Each section tests different skills and knowledge areas, requiring both conceptual understanding and mathematical problem-solving. The exam is designed to assess your understanding of calculus-based mechanics at a college level.

Section I: Multiple Choice Questions (MCQ)

The multiple-choice section contains 40 questions that must be completed in 45 minutes. This section accounts for 50% of your total AP score.

Question Format and Content

MCQ questions cover seven major content areas:

For calculators related to Kinematics, Newton's Laws of Motion, Work, Energy, and Power, Oscillations, and Gravitation, we refer to https://physicscalculators.net/.

Scoring the MCQ Section

Each correct answer earns 1 point. There is no penalty for incorrect answers, so you should answer every question, even if you're unsure. Your raw score is simply the number of questions you answer correctly (0-40). This raw score is then scaled to contribute 50% toward your final composite score.

Question Types

The MCQ section includes various question formats:

Section II: Free Response Questions (FRQ)

The free-response section contains 4 questions that must be completed in 45 minutes. This section also accounts for 50% of your total AP score, with FRQ 1 worth 10 points, FRQ 2 worth 12 points, FRQ 3 worth 10 points, and FRQ 4 worth 8 points (40 points total).

FRQ 1: Mathematical Routines - Points: 10 | Time Allocation: ~11 minutes

This question focuses on applying mathematical techniques to solve physics problems. You'll need to:

• Use calculus (derivatives, integrals, differential equations) to solve mechanics problems
• Apply mathematical techniques to analyze physical situations
• Perform calculations accurately and show your work clearly
• Demonstrate proficiency in calculus-based problem-solving

Scoring: Points are awarded for correct application of calculus techniques, accurate calculations, clear mathematical reasoning, and proper use of physics principles. Partial credit is available for incomplete but partially correct solutions.

FRQ 2: Translation Between Representations - Points: 12 | Time Allocation: ~11 minutes

This question requires you to translate between different representations of physical situations. You'll need to:

• Convert between graphs, equations, diagrams, and verbal descriptions
• Demonstrate understanding of how different representations relate to each other
• Use multiple representations to solve problems
• Show connections between mathematical and graphical representations

Scoring: Points are awarded for accurate translation between representations, correct interpretation of graphs and diagrams, appropriate use of equations, and clear demonstration of understanding relationships between different representations.

FRQ 3: Experimental Design and Analysis - Points: 10 | Time Allocation: ~11 minutes

This question asks you to design experiments, analyze experimental data, and evaluate experimental procedures. You'll need to:

• Design experiments to test physics principles
• Analyze experimental data and identify sources of error
• Evaluate experimental procedures and suggest improvements
• Apply experimental methodology to mechanics contexts

Scoring: Points are awarded for well-designed experiments, accurate data analysis, correct identification of sources of error, appropriate evaluation of procedures, and clear application of experimental methodology.

FRQ 4: Qualitative/Quantitative Translation - Points: 8 | Time Allocation: ~12 minutes

This question requires you to translate between qualitative reasoning and quantitative analysis. You'll need to:

• Explain physical phenomena both conceptually and mathematically
• Show how qualitative understanding connects to quantitative calculations
• Use conceptual reasoning to guide mathematical problem-solving
• Demonstrate understanding of physical principles through both qualitative and quantitative approaches

Scoring: Points are awarded for accurate qualitative explanations, correct quantitative calculations, clear connections between conceptual and mathematical reasoning, and appropriate use of physics principles in both qualitative and quantitative contexts.

Scoring Process and Weightings

The AP Physics C: Mechanics exam uses a weighted scoring system to ensure both sections contribute equally to your final score.

Raw Score Calculation

Your raw scores are calculated as follows:

• MCQ Raw Score: Number of correct answers (0-40 points)
• FRQ Raw Score: Sum of points from all 4 FRQs (0-40 points: FRQ 1 worth 10, FRQ 2 worth 12, FRQ 3 worth 10, FRQ 4 worth 8)

Score Weightings (2025 Guidelines)

According to the latest College Board guidelines, both sections are weighted equally:

• MCQ Section: 50% of total score (40 questions)
• FRQ Section: 50% of total score (4 questions worth 40 total points: FRQ 1 worth 10, FRQ 2 worth 12, FRQ 3 worth 10, FRQ 4 worth 8)

This equal weighting means that performing well on both sections is essential. Since FRQs are worth 40 total points compared to 40 MCQ questions, each point has equal impact on your final score.

Composite Score Calculation

Your raw scores from both sections are combined into a composite score using the following process:

Scaling Process

The College Board scales your raw scores to ensure equal weighting:

• MCQ Scaled Score: Your MCQ raw score (0-40) is scaled to 45 points
• FRQ Scaled Score: Your FRQ raw score (0-40) is scaled to 45 points
• Total Composite Score: Sum of scaled scores = 0-90 points

For example, if you score 30 out of 40 on MCQ and 28 out of 40 on FRQ:

• MCQ scaled: (30/40) × 45 = 33.75 points
• FRQ scaled: (28/40) × 45 = 31.5 points
• Composite score: 33.75 + 31.5 = 65.25 points (rounded to 65)

AP Score Conversion (1-5 Scale)

Your composite score (0-90) is converted to the final AP score of 1-5 using a statistical process called equating. This process accounts for exam difficulty and ensures scores are comparable across different exam administrations.
