About the AP Physics C: Electricity & Magnetism Exam
AP Physics C: Electricity and Magnetism is a calculus-based course covering electrostatics, conductors and capacitors, electric circuits, magnetic fields, electromagnetic induction, and Maxwell's equations. The course assumes prior completion of AP Physics C: Mechanics and concurrent or prior calculus coursework.
The exam runs 1 hr 30 min. The multiple-choice section has 35 questions and accounts for approximately 50% of the total score. The Free Response Questions (FRQ) accounts for the remaining 50%.
What Is a Good AP Phys C E&M Score?
About 75% of students earn a 3 or higher, with 31% earning a 5. Like AP Physics C: Mechanics, the high scores reflect a self-selected STEM-focused student population.
The College Board assigns a label to each score level. A 5 means Extremely Well Qualified, a 4 means Well Qualified, a 3 means Qualified, a 2 means Possibly Qualified, and a 1 means No Recommendation. Most colleges award credit only for scores of 3 or higher, with many competitive schools requiring 4 or 5 for the same credit.
AP Physics C: Electricity & Magnetism College Credit Policy
Most universities award 4 credits for scores of 4 or 5, satisfying the second semester of calculus-based physics required for engineering and physics majors.
Credit policies vary significantly between institutions. Some universities, particularly highly selective ones, use AP scores for placement rather than credit. That means they let you skip ahead in a course sequence but do not reduce your graduation credit requirement. Always verify with your specific school's registrar or AP credit chart before assuming your score earns a particular number of credits.
How Is the AP Phys C E&M Score Calculated?
The College Board converts raw scores into a composite score, then maps that composite to a final AP score of 1 to 5. The multiple-choice section is scored by counting correct answers. There is no penalty for wrong answers, so it always pays to attempt every question. Free response answers are scored by trained AP readers using detailed rubrics.
The exact composite-to-AP-score conversion (called the "raw score conversion chart") is set after each exam administration based on the difficulty of that year's exam. The cutoffs used in this calculator are based on historical averages and are intended as estimates. Your actual score will be determined by College Board after scoring is complete.
Frequently Asked Questions
Should I take AP Physics C: Mechanics before E&M?
Yes. AP Physics C: Mechanics is the standard prerequisite. The mathematical framework and problem-solving approach developed in Mechanics are directly applied throughout the E&M course.
Is AP Physics C: E&M harder than Mechanics?
Most students find E&M more conceptually difficult because electromagnetism is more abstract than mechanics. The 5-rate is similar to Mechanics because the same self-selected student population takes both exams.
Can I take AP Physics C: Mechanics and E&M in the same year?
Yes. Many students take both in the same academic year. The AP exams for both are offered on the same day back to back, so a student can complete both exams in a single 3-hour sitting.
Does AP Physics C: E&M count for electrical engineering programs?
Yes. Most electrical engineering programs accept AP Physics C: E&M for the second semester of physics credit. Combined with Mechanics, students can typically place out of the full introductory physics sequence.
What math is needed for AP Physics C: E&M?
AP Physics C: E&M requires comfort with differentiation, integration, and vector algebra. Conceptual understanding of line and surface integrals also helps. Concurrent enrollment in AP Calculus BC or higher is strongly recommended.
