AP Physics C: Mechanics

It is a hybrid digital exam. You complete multiple-choice questions and view free-response questions in the Bluebook app. You handwrite free-response answers in paper exam booklets. Calculators are permitted, and reference materials such as equation sheets and reference tables are available. The source announces 2027 section counts and timings but does not state current pre-2027 timings.

For the exam effective May 3, 2027, total time is 3 hours: Section 1 has 42 questions in 1 hour 25 minutes; Section 2 has 4 questions in 1 hour 35 minutes. The source does not state the current pre-2027 timings, so confirm your administration's schedule with your AP coordinator.

It is a calculus-based, college-level course, and the source recommends prior or concurrent calculus. Difficulty depends on your math preparation and lab experience. Expect to explain concepts, derive and calculate with units, create and interpret representations, and justify claims with evidence; those are the course's science practices.

Recommended prerequisite: you should have taken calculus or be taking calculus at the same time. The course is especially appropriate if you plan to specialize or major in a physical science or engineering. It is equivalent to a semester-long introductory calculus-based college physics course.

The seven units are organized in a commonly taught sequence, but your teacher may reorder them. A sensible default is to follow your class sequence: kinematics, force and translational dynamics, work-energy-power, linear momentum, torque and rotational dynamics, rotating-system energy and momentum, then oscillations. Revisit earlier units while practicing mixed problems and lab-style reasoning.

Do not treat it as an algebra-only course or memorize formulas without units. The exam expects calculus-based problem solving plus science practices: creating representations, deriving and calculating, designing experiments, and justifying claims. Skipping lab and graph work is risky because free-response questions include experimental design and analysis and representation translation.

Calculators are permitted; the source directs students to the AP Exams Calculator Policy for the approved list. Reference materials, including equation sheets and reference tables, are available for this course. Check the official reference information for your exam administration before test day.

The source does not promise credit or a specific score. It provides an AP Credit Policy Search to find colleges that grant credit or placement for AP Exam scores. Policies vary by school, so check each college's current policy rather than assuming credit.

The source does not describe a retake policy. Ask your AP coordinator and check your College Board account for available administrations and deadlines; do not rely on an unsupported claim that retakes are automatic or unlimited.
