AP Physics C: Mechanics Score Distribution 2026
AP Physics C: Mechanics is a calculus-based exam covering kinematics, dynamics, energy, rotation, and oscillation. About 28% of students score a 5 — higher than most AP exams, reflecting the highly self-selected test-taking population.
AP Physics C: Mechanics Score Distribution 2026

How the Composite Score Is Calculated
| Section | Content | Max Points |
|---|---|---|
| Section I — Multiple Choice | 35 questions (45 min); single-select only | 45 |
| Section II — Free Response | 3 questions (45 min): mix of derivation, experimental, multi-part | 45 |
| Total | 90 |
Both sections are weighted equally at 50% each. The free-response questions require calculus — integrals and derivatives appear directly in derivation steps — and partial credit is available at each step.
What Score Do You Need?
| Target | Composite Needed | Rough Strategy |
|---|---|---|
| 5 | 67/90 (74%) | ~26/35 MC + ~41/45 FRQ |
| 4 | 52/90 (58%) | ~20/35 MC + ~32/45 FRQ |
| 3 | 39/90 (43%) | ~15/35 MC + ~24/45 FRQ |
The Role of Calculus in Scoring
AP Physics C: Mechanics assumes students are concurrently taking or have completed Calculus BC. Calculus appears in three key places:
- Kinematics: Deriving position from velocity via integration; acceleration from velocity via differentiation.
- Work & Energy: Variable-force work integrals (∫F·dx).
- Rotational Dynamics: Moment of inertia integrals for continuous mass distributions.
On the FRQ section, writing the correct setup (free-body diagram + Newton's second law → differential equation → solution via integration) earns most of the points on a derivation problem, even if your algebra has an error. Partial credit is generous on setup steps.
The multiple-choice section tests both qualitative reasoning and quantitative calculation. Roughly half of MC questions can be answered with physics intuition alone; the other half require numerical work.
