Comparison with Other AP Science Exams (2024-2025)
When we compare AP Physics 1 to other science-based AP exams, the historical disparity becomes evident:
| AP Exam | Pass Rate 2024 | Pass Rate 2025 | Score of 5 (2025) |
|---|---|---|---|
| AP Physics 1 | 47.3% | 67.3% | 19.8% |
| AP Physics 2 | 66.2% | 68.5% | 14.1% |
| AP Chemistry | 51.2% | 53.8% | 13.0% |

Remarkably, AP Physics C: Mechanics—a calculus-based physics course often perceived as more advanced—has consistently had a higher pass rate than AP Physics 1. This counterintuitive finding provides crucial insight: the issue was not the physics content's inherent difficulty, but rather the unique combination of challenges the exam presented and student preparation levels.
Seven Key Reasons Why AP Physics 1 Was Historically the Hardest
1. Conceptual Understanding Over Formula Memorization
Unlike many science courses where memorizing formulas and definitions can yield reasonable scores, AP Physics 1 demands deep conceptual understanding. The College Board explicitly designed this exam to test whether students truly comprehend physical principles rather than merely applying equations mechanically.
Consider the difference between these two approaches to a momentum problem:
A memorization-based student might plug numbers into this formula. However, AP Physics 1 questions often ask students to explain why momentum is conserved, to predict what happens without calculating, or to describe what physical principle applies and why. This requires understanding that momentum conservation emerges from Newton's third law and applies only when external forces are negligible—a conceptual leap many students struggle to make.
2. Multi-Concept Integration Requirements
AP Physics 1 questions frequently require students to synthesize multiple concepts simultaneously. A single problem might involve:
- Kinematics (describing motion with equations)
- Newton's Laws (analyzing forces and free-body diagrams)
- Energy Conservation (tracking energy transformations)
- Momentum (applying conservation principles)
Students who have mastered each topic individually often struggle when required to determine which principles apply to a given situation and how they interconnect. This is fundamentally different from exams where topics are tested in isolation.
⚠️ Common Student Mistake
Many students learn physics topics in sequence and never practice integrating them. When the AP exam presents a scenario requiring both energy conservation AND momentum analysis, these students freeze because they've never practiced identifying when each approach is appropriate.
3. Mathematical Reasoning Without Calculus
AP Physics 1 is classified as "algebra-based," meaning calculus is not required. However, this classification is somewhat misleading. The exam requires sophisticated mathematical reasoning including:
- Proportional reasoning (if mass doubles, what happens to acceleration?)
- Algebraic manipulation (solving multi-variable equations)
- Graphical interpretation (extracting information from position-time, velocity-time, and force-time graphs)
- Trigonometric applications (component analysis of vectors)
Students with weak algebra skills find themselves unable to manipulate these equations effectively, even if they understand the physics conceptually. Paradoxically, the calculus-based AP Physics C course attracts students with stronger mathematical preparation, which partially explains its higher pass rate despite covering more advanced material.
4. Free Response Question Demands
The AP Physics 1 free-response section comprises 50% of the total score and includes five questions requiring:
- Experimental Design: Designing experiments to test hypotheses
- Quantitative/Qualitative Translation: Moving between mathematical and verbal descriptions
- Paragraph-Length Response: Writing coherent explanations of physical phenomena
- Short Answer: Providing concise, accurate responses
Many physics students excel at calculations but struggle with the verbal reasoning and written communication these questions demand. The requirement to explain and justify physical reasoning—not just produce correct numerical answers—catches many students off guard.
5. Breadth of Content Coverage
AP Physics 1 covers an extensive range of topics across seven units:
| Unit | Topic | Exam Weight |
|---|---|---|
| 1 | Kinematics | 12-18% |
| 2 | Dynamics (Newton's Laws) | 16-20% |
| 3 | Circular Motion & Gravitation | 6-8% |
| 4 | Energy | 20-28% |
| 5 | Momentum | 12-18% |
| 6 | Simple Harmonic Motion | 4-6% |
| 7 | Torque & Rotational Motion | 12-18% |
Each unit contains multiple subtopics that must be mastered. Unit 7 (Torque and Rotational Motion) is particularly challenging because it introduces rotational analogs to linear concepts students have just learned, requiring them to understand parallel structures while keeping the concepts distinct.
6. Student Population and Preparation Factors
Unlike AP Physics C, which typically attracts students who have already completed physics courses and have strong calculus backgrounds, AP Physics 1 often serves as students' first physics course. This creates several challenges:
- Students lack physics intuition developed through prior coursework
- Many students underestimate the mathematical demands
- Some schools recommend AP Physics 1 to students without adequate preparation
- The course is sometimes viewed as "easier" than AP Physics C, attracting students seeking to avoid calculus requirements
This self-selection pattern historically meant the AP Physics 1 test-taking population included many students who were underprepared for the exam's demands.
7. Exam Design Philosophy
The College Board redesigned AP Physics in 2014-2015, splitting the former AP Physics B into AP Physics 1 and AP Physics 2. The new design emphasizes "science practices" and authentic scientific reasoning over computational problem-solving. While educationally valuable, this approach:
- Requires different teaching methodologies than traditional physics courses
- Cannot be easily "crammed" through last-minute studying
- Devalues the formula-application skills many students have developed
- Demands skills (experimental design, scientific argumentation) that are less commonly taught
The Psychological Barrier: Why Physics Feels Different
Beyond technical challenges, AP Physics 1 presents unique psychological obstacles. Physics requires students to reconcile their everyday intuitions about how the world works with counterintuitive physical principles. Consider these examples:
🧠 Counterintuitive Physics Concepts
- Newton's First Law: Objects in motion stay in motion (but our experience suggests things naturally stop)
- Newton's Third Law: Action-reaction forces are equal (but it seems like a truck hitting a car should exert more force)
- Projectile Motion: Horizontal and vertical components are independent (but we don't intuitively separate them)
- Centripetal Force: Objects moving in circles don't experience "outward" force (despite the sensation we feel)
Overcoming these intuitive misconceptions requires not just learning new information but unlearning deeply held beliefs about how the physical world operates. This cognitive restructuring is more difficult than acquiring new knowledge in domains where students have fewer preconceptions.
Strategies for Success: How to Beat the Odds
Despite the challenges, many students successfully pass AP Physics 1 each year—and with the improved 2025 pass rates, your chances are better than ever. Based on data from successful students and research in physics education, we recommend the following strategies:
1. Prioritize Conceptual Understanding
For every equation you learn, ask yourself:
- What physical situation does this equation describe?
- What assumptions must be true for this equation to apply?
- How would I explain this concept to someone without using math?
- Can I draw a diagram representing this equation?
2. Practice Multi-Concept Problems
Seek out problems that require identifying which physics principles apply. These "synthesis" problems are more valuable than single-concept exercises. Focus particularly on connections between:
- Force analysis and kinematics
- Energy and momentum in collisions
- Rotational and linear motion parallels
- Graphical and mathematical representations
3. Master Free-Body Diagrams
The ability to correctly draw and interpret free-body diagrams is fundamental to success in AP Physics 1. Practice drawing FBDs for increasingly complex situations:
- Objects on inclined planes
- Connected objects (systems with pulleys, strings)
- Objects in circular motion
- Objects experiencing friction
4. Develop Written Explanation Skills
Practice writing paragraph-length explanations of physical phenomena. Your explanations should:
- Identify the relevant physics principle
- State why that principle applies
- Connect the principle to the specific situation
- Reach a logical conclusion
5. Use Past FRQs Extensively
The College Board releases past free-response questions with scoring guidelines. Study both the questions and the rubrics to understand exactly what earners look for. Pay attention to:
- How points are allocated
- What justifications are required
- Common student errors noted in scoring commentaries

Common Mistakes to Avoid
Based on our experience tutoring AP Physics 1 students, here are the most common mistakes that lead to low scores:
- Memorizing formulas without understanding: Knowing equations is necessary but insufficient. You must understand when and why to apply them.
- Neglecting units: Unit analysis is a powerful tool for checking your work. If your answer has wrong units, your approach is flawed.
- Ignoring free-body diagrams: Many students skip this step and go straight to equations, leading to missed forces and sign errors.
- Rushing through problems: Physics problems reward careful analysis. Reading quickly and missing key information is a common pitfall.
- Inconsistent sign conventions: Establish your positive direction at the start and maintain it throughout the problem.
- Not practicing FRQs: Multiple-choice practice alone is insufficient. FRQs require different skills that must be developed through practice.
- Waiting until spring to start serious preparation: AP Physics 1 content builds cumulatively. Gaps from early in the year will haunt you later.
