35 questions in 90 minutes, worth 50% of the total score. This section tests your ability to apply calculus-based physics principles to diverse physical scenarios. Time management is critical, as you must solve problems accurately under pressure.
3 questions in 90 minutes, worth 50% of the total score. These multi-part problems require you to derive expressions, interpret graphs, and perform complex calculations. One question is typically a laboratory-based scenario.
A table of information and a table of equations are provided. A four-function, scientific, or graphing calculator is permitted on the entire exam. Mastery of calculus-based derivation and graphical analysis is essential.
Unit-by-Unit Breakdown
Calculus-Based Motion & Dynamics
We drill students to identify the fundamental conservation law (Energy, Momentum, or Angular Momentum) or dynamical law (Newton's Second Law) before writing any equations, ensuring every derivation is grounded in physical reality.
For Mechanics, we master the transition between differentiation (position to velocity to acceleration) and integration (acceleration to velocity to position). We focus on setting up correct integral bounds, a common point-loss area on FRQs.

Coaching for Flawless Rotational & Periodic Analysis

Torque, moment of inertia, and angular acceleration. We teach students how to set up $\tau_{net} = I\alpha$ and account for parallel-axis theorem shifts.
Conservation of angular momentum in collision scenarios. Mastering the distinction between point particles and extended rigid bodies is a frequent FRQ differentiator.
Simple Harmonic Motion (SHM) for springs and pendulums. We emphasize energy transformation between kinetic and potential, and correctly identifying the period $T$.
Torque
Angular Momentum
Simple Harmonic Motion
Moment of Inertia
The conceptual gaps between linear and rotational kinematics, and the energy storage in oscillating systems (springs/pendulums) dictate your ability to model complex motion. These subtle nuances in torque and angular momentum are heavily targeted in both MCQ and FRQ sections. We drill students using scenario-based practice profiles until they can confidently classify physical systems, isolate force interactions, and justify any rotational model in under 60 seconds.
Concepts & Practice

Complex mechanics problems appear across all FRQs. Our tutors focus on showing clear derivation steps and using standard physics notation to secure full points.

FRQ Strategies for Maximizing Rubric Points
FRQs are where the exam is won or lost. Precise vocabulary is mandatory.
Many points are awarded for stating the relevant physics principle (e.g., 'By Conservation of Mechanical Energy, K_i + U_i = K_f + U_f'). Never start with a complex equation without justifying which law you are applying.
AP Physics C is calculus-based. If a force is non-constant or a variable changes over time/distance, you must set up the integral rather than using simple algebraic formulas. Show the integral setup explicitly.
A free-body diagram (FBD) is often worth rubric points. Ensure all vectors are clearly labeled, the coordinate system is defined, and the diagram is large enough to be easily readable by the grader.
Derivations are a staple of the FRQ section. Do not skip steps; show the algebraic manipulation clearly. If you are asked to show that an expression is true, start from a known physical law and work toward the final result.
For lab-based FRQs, always identify which variables are being plotted to create a linear graph. Explain that the slope or y-intercept corresponds to the physical constant being measured.
College Board rubrics heavily favor symbolic manipulation over raw numeric calculation. If you plug in numbers at the start and make a calculation error, you lose access to most of the points for the derivation. We drill students to carry variables (e.g., 'm', 'g', 'h') through the entire process and only substitute values at the very final step.
Writing "plugging in numbers too early" instead of "derive symbolic expressions first".
Calculus-Based Tools
Used for work, center of mass, and non-constant force calculations.
Used to find velocity/acceleration from position and forces from potential energy.
Breaking forces into components (sin/cos) for FBD analysis.
Standard tools for constant acceleration scenarios.
Specific formulas for discs, spheres, rods, etc.
Energy, Linear Momentum, and Angular Momentum templates.
Ď = r Ă F and Ď = IÎą for rotational problems.
T = 2Ďâ(m/k) or T = 2Ďâ(L/g) for oscillating systems.
Never plug in numbers until the final step. Symbolic manipulation is essential for earning full credit.
Be prepared to set up integrals for non-constant forces, work, or moments of inertia.
Always keep track of units (SI) and use the provided constant table to avoid minor precision errors.

âI was scoring a 2 on AP Chemistry practice tests in January. By May I had a 5. Pooja ma'am focus on the FRQ rubric was the thing that made the biggest difference, I'd never understood how strictly it was marked.â

âPrannoy sir helped me go from a 3 to a 5 in AP Calculus BC. The sessions were intense but the way he broke down FRQ justification was completely different from what my school taught. I finally understood what 'show your work' actually means for College Boardâ
