AP Physics C: E&M score calculator.
Enter how many multiple-choice questions you got right and your three free-response scores. We turn that into a predicted 1 to 5 using estimated cut scores, and show the composite points behind it.
Tuned for AP Physics C: E&M.
The Electricity and Magnetism exam, the second half of AP Physics C, splits evenly between 35 multiple-choice questions and three free-response problems. This AP Physics C E&M score calculator mirrors that 50/50 weighting and uses estimated cut scores modeled from recent exams.
Frequently asked questions
Quick answers — written by humans, not a chatbot.
Is this the same format as Physics C: Mechanics?
Yes. Both Physics C exams have 35 multiple-choice questions and three free-response problems, weighted evenly. The content differs, electricity and magnetism here versus mechanics there, but the scoring shape is identical.
Why does Physics C have a forgiving curve?
A small, well-prepared group takes the calculus-based exam, and the questions are demanding, so the raw percentage needed for each score often runs lower than students expect. Treat the result as an estimate.
Should I count partial credit on the free response?
Yes. Each problem is graded point by point against the rubric, so add up the points you would realistically earn instead of scoring a problem all or nothing.
