AP Physics 1 is one of the more challenging AP courses, and the score data backs that up. In 2025, only 19.8% of test-takers earned a 5, and 19.2% scored a 1, the lowest possible mark. That’s a wider spread at the bottom than you’ll find in most other AP subjects. The course is genuinely difficult, but the reasons it trips students up are specific and manageable once you understand them.
What the Pass Rate Tells You
A useful way to gauge difficulty is to look at how many students score a 3 or higher, since that’s the threshold most colleges consider for credit. In 2025, about 62.7% of AP Physics 1 students hit that mark. That’s lower than AP sciences like Biology and Chemistry, which tend to cluster more students in the 3-to-5 range. The course consistently lands near the bottom of AP pass-rate rankings year after year, not because it covers the hardest math, but because of how the exam tests you.
Why It Feels Harder Than Other AP Sciences
AP Physics 1 is algebra-based, meaning you won’t need calculus. On paper, that sounds easier than AP Physics C, which requires it. In practice, the opposite is often true. Because you can’t lean on calculus shortcuts, the exam forces you to reason through problems conceptually. You need to explain why something happens, not just plug numbers into a formula.
The College Board describes the course as built around “science practices” that teach you to think like a physicist. That means creating diagrams to represent physical situations, deriving symbolic expressions through logical steps, and designing experimental procedures to answer scientific questions. A typical exam problem might give you a scenario and ask you to write a paragraph justifying your answer, or to sketch a graph showing how one variable changes over time. Students who’ve done well in math-heavy courses by memorizing formulas often struggle with this style of questioning.
The topics themselves, including kinematics, forces, energy, momentum, rotation, and simple harmonic motion, aren’t exotic. But each one builds on the last. If you don’t fully grasp Newton’s second law, you’ll struggle with circular motion, which means you’ll struggle with rotational dynamics later. The course punishes gaps in understanding more than most AP classes do.
Math You Actually Need
The College Board recommends that you’ve completed geometry and are at least taking Algebra II at the same time. You won’t see integrals or derivatives on this exam. What you will need is comfort with algebraic manipulation: solving for variables, working with ratios, interpreting graphs, and using basic trigonometry (sine, cosine, tangent for force components and angles).
Where students get caught off guard is not the math itself but the translation step. A problem might describe a ball rolling off a table, and you have to figure out which equations apply, define your coordinate system, and solve symbolically before touching any numbers. That process of turning a physical scenario into a solvable math problem is the core skill of the course, and it takes practice to develop.
What Makes the Exam Tricky
The AP Physics 1 exam is three hours long and split into two sections. The multiple-choice section includes standalone questions and sets tied to a shared scenario, like an experiment or data table. Many questions have five answer choices instead of the usual four, and some ask you to select two correct answers.
The free-response section is where most students lose points. You’ll face questions that ask you to design an experiment, derive an equation, or write a qualitative argument explaining a physical phenomenon. Partial credit is available, but graders are looking for clear reasoning. Writing “because of conservation of energy” without explaining how energy is conserved in that specific situation won’t earn full marks.
This emphasis on written justification is unusual for a science exam. Students who treat it like a math test, showing calculations but skipping the reasoning, tend to underperform relative to their actual understanding.
How to Succeed in the Course
The single most effective habit is solving problems without looking at the solution first. Read the problem, draw a diagram, identify the relevant principles, and work through it on your own. Checking the answer afterward is fine, but the learning happens during the struggle. Students who passively read through worked examples often feel confident until exam day.
Focus on understanding principles rather than memorizing equations. The exam provides a formula sheet, so you don’t need to recall that kinetic energy equals one-half mv squared. What you do need is the ability to recognize when to apply it and how to connect it to the broader idea of energy conservation in a given scenario.
Lab work matters more than in other AP courses. The exam frequently asks you to describe how you’d set up an experiment, identify sources of error, or predict what a graph of collected data would look like. If your school does hands-on labs, pay attention to the methodology, not just the results. If your school doesn’t emphasize labs, look for virtual simulations that let you manipulate variables and observe outcomes.
Finally, practice the written justification questions early and often. Get comfortable writing short, precise paragraphs that connect a physics principle to a specific situation. A good format is: state the principle, explain how it applies to the scenario, and describe the outcome. This skill improves quickly with repetition, and it’s the biggest differentiator between students who score a 3 and those who score a 4 or 5.
Who Should Take It
AP Physics 1 is a strong choice if you’re interested in engineering, medicine, computer science, or any STEM field, since many college programs expect physics exposure. It’s also worth taking if you enjoy problem-solving and want to develop analytical thinking skills that transfer well beyond physics.
If you’re currently struggling with Algebra I or geometry, the course will feel overwhelming. The math isn’t advanced, but it needs to be automatic so you can focus on the physics concepts layered on top. Students who wait until they’re comfortable with Algebra II-level math tend to have a much better experience. Taking the course a year later and doing well is a smarter move than taking it early and earning a low score.
