AP Physics C: Electricity and Magnetism Practice Test
AP Physics C: Electricity and Magnetism is the calculus-based companion to Mechanics. After the 2025 redesign the exam is 3 hours hybrid digital — 40 MCQs in Bluebook (1hr 20min, 50%) and 4 handwritten FRQs (1hr 40min, 50%). Gauss's law, Ampère's law, and Faraday's law sit at the center of the course.

Upload the first examHow AI scoring works
When you upload an AP Physics C: Electricity and Magnetism PDF without an answer key, our system uses Google Gemini to read the document, extract every multiple-choice question, and generate the correct answers. The first attempt seeds the answer key; later attempts use the saved key, so AI runs only once per exam.
Each question is scored against the stored key in real time. After you submit, you can review every wrong answer with an AI-written explanation that grounds the reasoning in the original PDF page.
AI-generated keys may have errors. Always cross-check answers against an official source for high-stakes review.
Physics C: E&M FAQ
- Did Physics C: E&M change recently?
- Yes — the 2025 redesign expanded the course (now 3 hours, formerly 1.5 hours) and aligned the format with Physics 1/2: 40 MCQs (50%) + 4 FRQs (50%).
- Is Physics C: E&M harder than Mechanics?
- Most students agree it is harder. The mathematics is more abstract (vector calculus, flux integrals) and the concepts (fields, induced EMF) are less intuitive than mechanics.
- Can I take E&M without taking Mechanics?
- Technically yes, but it is unusual. Most schools teach Mechanics first and E&M in the second semester or second year.
- Which AP Physics path is best for engineering?
- Both Physics C exams are the strongest preparation for college engineering programs and may earn calculus-based physics credit.
