Estimate Your AP Physics C: E&M Score
The AP Physics C: Electricity and Magnetism exam is known for its rigor, covering complex concepts from electrostatics to electromagnetism. Understanding how your performance on different sections translates to a final score of 1-5 is crucial for gauging your progress. This calculator helps you estimate your score based on your performance on the multiple-choice and free-response sections.
How the AP Physics C: E&M Score is Calculated
The College Board converts your raw scores from the two sections of the exam into a single composite score out of 90. This composite score then determines your final AP score on a scale of 1 to 5.
Exam Structure:
- Section I: Multiple-Choice (MCQ): This section has 35 questions, you have 45 minutes to complete it, and it accounts for 50% of your total exam score. There is no penalty for incorrect answers.
- Section II: Free-Response (FRQ): This section consists of 3 questions, you have 45 minutes, and it also accounts for 50% of your exam score. Each question is typically worth 15 points.
Scoring Formula:
- MCQ Weighted Score: Your number of correct MCQ answers is scaled to be worth 45 points. The formula is:
(Number of Correct MCQs / 35) * 45
- FRQ Raw Score: This is the simple sum of the points you earned on the three FRQ questions. The maximum is 45 points (15 points per question).
- Composite Score: The final composite score is the sum of the weighted MCQ score and the raw FRQ score, with a maximum of 90 points.
Composite Score = MCQ Weighted Score + FRQ Raw Score
Example Calculation
Let's say a student achieves the following:
- Correct MCQ answers: 29 out of 35
- FRQ 1 Score: 12 out of 15
- FRQ 2 Score: 10 out of 15
- FRQ 3 Score: 8 out of 15
The calculation would be:
- MCQ Weighted Score = (29 / 35) * 45 = 0.82857 * 45 = 37.29
- FRQ Raw Score = 12 + 10 + 8 = 30
- Composite Score = 37.29 + 30 = 67.29 out of 90
Based on historical data, a composite score of 67.29 would likely result in an AP Score of 5.
Estimated Score Conversion
The composite score ranges for each AP score can vary slightly from year to year based on the difficulty of the exam. The following are typical, estimated ranges:
- Score of 5 (Extremely well qualified): 58 – 90
- Score of 4 (Well qualified): 45 – 57
- Score of 3 (Qualified): 34 – 44
- Score of 2 (Possibly qualified): 25 – 33
- Score of 1 (No recommendation): 0 – 24
