How This AP Physics C: E&M Score Estimator Works
This calculator uses a weighted model to estimate your AP Physics C: E&M score:
- MCQ contribution: (Correct answers / 35) x 50 = MCQ composite points
- FRQ contribution: (FRQ points / 45) x 50 = FRQ composite points
- Total composite: MCQ contribution + FRQ contribution (out of 100)
- Score mapping: The composite is compared against estimated thresholds to determine your 1-5 AP score range.
Both sections are weighted equally at 50% each.
