AP Physics C,
calculus-based
for engineers.
The calculus-based AP physics course. Mechanics (C: Mech) and Electricity & Magnetism (C: E&M) — two separate exams taken by students heading into engineering, physics and quantitative STEM at top US universities.
Calculus-based physics for engineering-bound students. Two exams: Mechanics and E&M. The most respected AP science for STEM admissions.
Physics C is the engineering-track AP physics.
AP Physics C consists of two separate exams: Mechanics (C: Mech) and Electricity & Magnetism (C: E&M). Both are calculus-based and both are significantly harder than Physics 1/2. A 5 on either — or both — is one of the strongest STEM signals a Vietnamese student can put on a US college application.
Two exams, one afternoon
Both Physics C exams are offered on the same day. Students can sit Mechanics only (90 min), E&M only (90 min), or both (back-to-back, 3 hours). We recommend taking both if the student has strong Calc AB/BC preparation.
The full content we cover in 1:1 lessons.
Every Times Edu AP Physics C mentor maps lessons directly to the College Board Course and Exam Description — nothing on the May exam is a surprise.
Kinematics
Position, velocity, acceleration with calculus (derivatives, integrals).
Newton's Laws
Force analysis, circular motion, friction with calculus.
Work, Energy, Power
Work-energy theorem using integration.
Momentum & Rotation
Angular momentum, torque, moment of inertia, rotational dynamics.
Electrostatics
Coulomb's law, electric fields, Gauss's law, potential.
Circuits
RC circuits, Kirchhoff's laws, capacitors.
Magnetism
Biot-Savart, Ampère's law, Faraday's law, inductors.
EM Waves
Maxwell's equations conceptual, electromagnetic radiation.
Exactly what the May exam tests.
Knowing the format and rubric is half the battle. Here is the full breakdown of the AP AP Physics C exam.
Mechanics MCQ
35 multiple-choice questions on calculus-based mechanics.
Mechanics FRQ
3 multi-part free-response problems with full calculus.
E&M MCQ
35 multiple-choice questions on electricity and magnetism.
E&M FRQ
3 multi-part free-response problems with full E&M calculus.
Why even strong students miss a 5.
These are the three traps we see most often in AP AP Physics C diagnostics — and every one is fixable with focused coaching.
Calculus integration errors
Physics C FRQs require real calculus — setting up and evaluating integrals for work, electric field, flux. A single setup error cascades through the entire problem.
Gauss's law surface selection
Choosing the wrong Gaussian surface makes E&M problems unsolvable. We teach the three canonical surface choices and when to use each.
Moment of inertia
Rotational dynamics problems require knowing or deriving moments of inertia. Students who memorise without understanding lose marks on non-standard shapes.
From diagnostic to May exam.
Two 5s on Physics C Mech and E&M. Times Edu's Gauss's law drills alone saved me 10+ points on the E&M exam. Best AP coaching I had.

Should my child take Mechanics only or both Mech + E&M?
For most engineering-bound students, we recommend both. If time is limited, Mechanics alone is sufficient for most US university credit. E&M is harder but more valued for electrical engineering and physics programmes.
Does my child need Calc BC for Physics C?
Calc AB is sufficient for Mechanics. E&M benefits from BC-level series and integration techniques. Most of our Physics C students take Calc BC in parallel.
How is Physics C different from Physics 1?
Physics C is calculus-based and goes much deeper into mechanics and E&M. Physics 1 is algebra-based and broader but shallower. Engineering students should take C; pre-med students should take 1.
Can Physics C earn college credit?
Yes — a 5 on Mechanics typically earns credit for first-semester university physics; a 5 on E&M earns credit for second-semester. This can save a full year of physics at many US universities.
