AP Physics C: Electricity and Magnetism Score Calculator

Enter your points from a Physics C: E&M practice test to predict your 1–5 score. A 5 takes about 70 of 100 points.

How the AP Physics C: Electricity and Magnetism exam is scored

The exam is 3 hours long. Multiple choice (42 questions) is 50% of your score and free response is 50%. The free response has four questions: two worth 10 points, one worth 12 and one worth 8. Each part is scaled by its weight and added into a composite out of 100, which is then converted to a score from 1 to 5.

What does it take to get a 5?

About 70 of 100 composite points, by our estimate. One way to get there is roughly 30 of 42 multiple choice questions right and 28 of 40 free-response points. A 4 takes about 59 points and a 3 about 47. In 2026, 24% of students earned a 5 and 75% earned a 3 or higher.

Where students lose points

Expect Gauss's law, Ampère's law, and RC or RL circuits set up with integrals or differential equations. Points come from starting with the right law, so write it down before plugging anything in. A 5 takes a smaller share of the points than on most AP exams.

About the calculator

How the estimate works and how to use it

Enter the points you expect on each part of the exam. Each section is weighted the way the College Board weights it, added into a total out of 100, and compared with estimated cut scores for a 5, 4, 3, and 2.
It is an estimate. The College Board sets new cut scores every year and does not publish them. Ours are based on the estimates other AP score calculators publish, so your real score can land a point either side.
The College Board's official AP score distributions for the most recent exam year.
Grade a practice free response with its scoring guidelines, the way AP readers do. The College Board posts past free-response questions with their scoring guidelines on AP Central.
Most colleges give credit for a 3 or higher, and selective colleges often ask for a 4 or 5. Check your college's AP credit policy for the exact rule.
Usually in early July, after the May exams. You see them in your College Board account.
