AP Physics C: Mechanics Score Calculator 2026
Enter your section scores for AP Physics C: Mechanics to estimate your 1–5 AP score.
Estimate. The College Board does not publish composite cutoffs, so these lines are reconstructed from released exams and third-party curves. Treat it as a prediction, not a guarantee.
AP Physics C: Mechanics covers the same mechanics topics as Physics 1 but with calculus, and that's the whole point: position, velocity, and acceleration are derivatives and integrals of each other, and the exam expects you to use that. For 2025 it became its own exam session with a longer format. It's narrower than Physics 1 but deeper, and it assumes you're taking calculus alongside it.
Inside the AP Physics C: Mechanics exam
Section I is 40 multiple-choice questions in 80 minutes (50%). Section II is four free responses in 100 minutes (50%), worth 10, 12, 10, and 8 points. The content spans kinematics, Newton's laws, work and energy, momentum, rotational motion, oscillations, and gravitation, all with calculus. As of the 2025 redesign, Mechanics has its own dedicated testing session rather than sharing one with Electricity and Magnetism.
How the AP Physics C: Mechanics score is calculated
AP Physics C: Mechanics combines these sections into one composite out of 90:
- Multiple choice: out of 40, weighted 50% of the composite.
- Free response: out of 40, weighted 50% of the composite.
Estimated score ranges
- 5: composite ≈ 53–90
- 4: composite ≈ 39–52
- 3: composite ≈ 32–38
- 2: composite ≈ 20–31
- 1: composite below 20
These ranges are estimates from past released exams. Use them to see how close you are to the next score, not as an official guarantee.
How to squeeze out more points
- Use calculus language on the free response. Write the integral or derivative even if you approximate the result; a correct setup, like impulse as the integral of force over time, often earns most of the credit.
- Know the kinematic relationships as calculus. Velocity is the derivative of position and the integral of acceleration; questions routinely hand you one and ask for another.
- Don't neglect rotation. Rotational kinematics, torque, moment of inertia, and angular momentum are a large slice of the exam and a common free response.
- Keep your basic calculus sharp. Weak integration on test day turns otherwise straightforward problems into dead ends.
Where students lose points
- Avoiding the calculus and reaching for constant-acceleration formulas. Those shortcuts fail when acceleration varies, which is exactly what the exam tests.
- Writing only a final answer. Like all AP physics, the rubric rewards the setup and method, so show the integral or the free-body diagram.
- Skipping the free-body diagram. Many mechanics problems start with one, and leaving it out loses easy points and invites sign errors.
- Sign errors in energy and momentum. A quick note to check signs saves careless points.
A worked example
On the usual estimated curve a composite near 53 of 90 has landed a 5, with a 3 around 32, a generous line that reflects how hard the exam is. The two sections each count for half. Enter your scores above to see where you stand and how close the next score is.

Frequently asked questions
- How is the AP Physics C: Mechanics exam scored?
- Each section is weighted into a composite out of 90: Multiple choice out of 40 (50%); Free response out of 40 (50%). The composite then maps to a 1–5 score.
- What composite do I need for a 5 on AP Physics C: Mechanics?
- On our estimated curve, roughly 53+ (out of 90) is a 5, 39+ is a 4, 32+ is a 3, and 20+ is a 2. These shift slightly every year.
- Is this the official AP curve?
- No. The College Board equates each administration to keep scores comparable across years, and it does not publish the composite cutoffs. These lines are reconstructed from released exams and widely-cited third-party curves, so treat them as an estimate.
- What is a good AP score?
- A 3 is considered qualified and earns credit at many colleges; 4s and 5s are strong and accepted more widely, including at selective schools.
- Do I need calculus for AP Physics C: Mechanics?
- Yes. The course is calculus-based, and the exam expects you to differentiate and integrate, for example treating velocity as the derivative of position. Most students take it alongside or after a calculus course.
- Is AP Physics C: Mechanics harder than Physics 1?
- It covers a narrower set of mechanics topics but in more depth and with calculus, so it's more demanding. The curve is correspondingly generous; the composite needed for a 5 is a relatively low share of the total.
