AP Physics C: Electricity and Magnetism - Study Guides, Flashcards, AP-style Practice & Mock Exams

The exam has two 45-minute sections, each worth 50% of your score. You will first complete 35 multiple-choice questions (MCQs), which test a breadth of knowledge. This is followed by three free-response questions (FRQs) that require in-depth problem-solving, including derivations and explanations.

The FRQs test a range of skills, often combining them in one question. You must be prepared to perform mathematical routines to solve problems, justify claims with evidence (argumentation), and sometimes analyze an experimental design. One FRQ is typically based on an experimental scenario.

A structured approach is most effective for mastering all 31 topics. We recommend working through each of the 6 units sequentially, using our AP-style quizzes to check your understanding. Then, consolidate your knowledge with unit exams before attempting the full-length mock exam to simulate test day.

Calculus is fundamental to this course and is tested extensively. You must be proficient in applying both differential and integral calculus to solve problems. Key skills include setting up and evaluating integrals for physical quantities and using derivatives to analyze theoretical relationships between variables.

No, you do not need to memorize every formula, as an official equation sheet is provided for the exam. However, you must understand the context and meaning of each equation. True mastery involves knowing which formula to apply and how it represents a specific physical relationship.

Yes, a graphing calculator is permitted and recommended for both the multiple-choice and free-response sections. While it is a powerful tool for calculations, remember that on the FRQs, credit is awarded for showing your work, including the initial setup of equations and any symbolic derivations.

Success requires strong problem-solving and analytical abilities. Key science practices include using mathematical routines to solve complex problems, data analysis from experimental setups, and argumentation to justify claims with evidence. These skills are more critical than simple memorization of facts or equations.

The multiple-choice and free-response sections are weighted equally, each accounting for 50% of your final composite score. To achieve a high score, you must demonstrate proficiency in both the broad conceptual knowledge tested in the MCQs and the deep analytical skills required for the FRQs.

You have 45 minutes for each section. For the 35 MCQs, this averages to about 75 seconds per question. For the three FRQs, you have an average of 15 minutes per question. It is a good strategy to quickly scan all three FRQs and begin with the one you feel most confident about.

The course focuses on the core principles of electricity and magnetism using calculus. You will explore major topics including electrostatics, conductors and capacitors, DC circuits, magnetic fields, and electromagnetism (including Maxwell's Equations). The curriculum is designed to be equivalent to a semester-long, university-level physics course.
