AP Physics C: Electricity and Magnetism score calculator
Enter how many multiple-choice questions you expect to get right and your points on each free-response question. The calculator weights each part the way the May 2027 exam does and estimates your 1–5 score.

You're within a few points of a cutoff, so a 4 or a 5 are both realistic. Cutoffs move from year to year.
How the Physics C: E&M exam is scored
Each part counts for a fixed share of the composite. Raw points become a share of that part, then the shares add up to 100.
| Part | Length or points | Share of the score |
|---|---|---|
| Multiple choice | 42 questions, 85 minutes | 50% |
| Mathematical Routines | 10 points | 12.5% |
| Translation Between Representations | 12 points | 15% |
| Experimental Design and Analysis | 10 points | 12.5% |
| Qualitative/Quantitative Translation | 8 points | 10% |
Where the 1–5 estimate comes from
College Board doesn't publish the composite score needed for each AP score, and the cutoffs shift a few points every year. The estimate uses the cutoffs from College Board's 2012 released AP Physics C: Electricity and Magnetism exam, converted to a share of the total so they fit today's section weights. The exam's format has changed since then, so the cutoffs are a rough guide. Within 3 points of a cutoff, the calculator shows both scores.
