Advanced Placement (AP) Physics help — done properly
AP Physics splits into algebra-based (Physics 1 + 2) and calculus-based (Physics C: Mechanics + E&M). Physics 1 is the most-failed AP exam — partly because students underestimate it. C: E&M is the hardest by far but the curve is generous.
Exam format you'll actually sit
Physics 1 & 2: 50 MCQ + 5 FRQs, 3h. Physics C: Mech: 35 MCQ + 3 FRQs, 1h 30. Physics C: E&M: same. All scored 1-5.
Highest-yield topics (the ones that show up year after year)
- Kinematics (1D and 2D motion, projectiles)
- Newton's laws + free body diagrams
- Energy and momentum conservation
- Rotational motion + torque (Physics 1 + C)
- Simple harmonic motion + waves
- Electrostatics + circuits (Physics 1 + 2)
- Magnetism + electromagnetic induction (Physics 2 + C: E&M)
- Calculus: Gauss's law, Ampere's law (Physics C: E&M only)
Drill these first. If you can't do every one of these cold, work through them with /explain or /problem-variants.
Common mistakes that quietly cost marks
- FRQ: forgetting to draw a free body diagram even when not explicitly asked
- Confusing average velocity with instantaneous velocity
- Forgetting that g points downward (negative if up is positive)
- Physics C: E&M: surface integrals direction errors
- Lab questions: not identifying systematic vs random error
When you mark your past papers, tag each lost mark to one of these. The pattern reveals where to focus.

Realistic study plan
Conceptual mastery first (Newton's laws, energy conservation). Then numerical practice. From January, alternate FRQs and full mocks.
