AP Physics C Mechanics review: exam format, the 7 units, and how to study

What’s on the AP Physics C Mechanics exam

The AP Physics C Mechanics exam splits evenly into two sections. Section I is 40 multiple-choice questions in 80 minutes, worth 50%. Section II is 4 free-response questions in 100 minutes, also 50%, where you write out full, calculus-based solutions. The whole exam runs about 3 hours.

It is calculus-based, so the questions expect you to differentiate and integrate, and a calculator and the official equation sheet are allowed on both sections. The format is hybrid — the multiple choice is in the Bluebook app while the free response is handwritten. One note on currency: the College Board is updating the multiple-choice count and timing beginning with the May 2027 exam, so confirm the current-year numbers before test day. Our equation sheet shows exactly what you are given.

The 7 units of AP Physics C Mechanics

The redesigned course covers seven calculus-based units. Force and translational dynamics is the heaviest and the one students find toughest; gravitation and orbits are folded into the dynamics and energy units.

How AP Physics C Mechanics is scored

Your multiple-choice and free-response points combine into one composite score, which the College Board scales to a 1–5 each year. Encouragingly, AP Physics C Mechanics is one of the highest-scoring AP exams — recent pass rates have sat around three-quarters of test-takers, and a large share earn a 5. That partly reflects a small, well-prepared cohort, so do not mistake the high pass rate for an easy exam.

How to study for AP Physics C Mechanics

Command the calculus first. Because the equation sheet is provided, points come from setting up the right derivative or integral and justifying it — not from recall. Practice deriving results rather than memorizing them, and get comfortable switching between an energy approach and a force approach.

Then put most of your reps into the free response, since it is half the exam and rewards clear, justified work. Drill past questions against the rubric with our AP Physics C Mechanics FRQ guide, and keep the equation sheet open so the symbols and setups feel automatic.

When is the AP Physics C Mechanics exam, and how long is it

AP Physics C Mechanics is given once a year during the College Board’s May testing window, and the exam takes about 3 hours. The exact date and start time are set each year, so confirm the current schedule on the official AP calendar with your coordinator before you plan around it.
