Estimate your 2024 AP Physics C: Electricity and Magnetism exam score based on practice test performance.
How the AP Physics C: E&M Score is Calculated
The AP Physics C: Electricity and Magnetism exam is notoriously challenging, often featuring the most aggressive "curves" in the AP program. The exam consists of two main sections, each weighted at 50% of your total score.
1. Multiple Choice Section (MCQ)
There are 35 multiple-choice questions to be completed in 45 minutes. Each correct answer is worth approximately 1.43 points toward your composite score. There is no penalty for guessing, so you should always answer every question.
2. Free Response Section (FRQ)
The FRQ section consists of 3 questions, each worth 15 points, for a total of 45 raw points. This section is also weighted at 50%, meaning each raw point in the FRQ section is worth approximately 1.11 points toward your composite score.
Score Distribution Table
| Composite Score Range | AP Score | Performance Description |
|---|---|---|
| 50 – 100 | 5 | Extremely Well Qualified |
| 38 – 49 | 4 | Well Qualified |
| 31 – 37 | 3 | Qualified |
| 20 – 30 | 2 | Possibly Qualified |
| 0 – 19 | 1 | No Recommendation |
Realistic Scoring Example
If a student correctly answers 22 questions on the MCQ and earns 25 points total across the three FRQ questions:
- Weighted MCQ: 22 × 1.4286 = 31.43
- Weighted FRQ: 25 × 1.1111 = 27.78
- Composite Score: 31.43 + 27.78 = 59.21
- Final AP Score: 5 (This student comfortably achieved a 5!)
Preparation Tips for E&M
To maximize your score, focus heavily on Gauss's Law and Ampere's Law, as these conceptual pillars appear frequently. Because the time limit is extremely tight (45 minutes per section), practicing with a timer is essential. Most students find they don't need to get every question right to earn a 5; usually, getting around 55-60% of the total available points is enough to secure the highest grade.
