Advanced Placement (AP) exams are designed to assess a student's readiness for college-level work in specific subjects. The scoring process for most AP exams involves combining raw scores from different sections (typically Multiple Choice and Free Response) and then converting these into a standardized score on a scale of 1 to 5.
This calculator provides an *estimation* of your final AP exam score based on your raw performance in the Multiple Choice (MCQ) and Free Response (FRQ) sections. It's important to note that the exact conversion formulas can vary slightly year to year and by subject, as the College Board adjusts them to maintain score comparability. However, this calculator uses a common methodology to give you a good approximation.
How the Calculation Works:
Raw Score Calculation: Your raw score is the sum of points earned in each section.
Section Weighting: AP exams typically weight the Multiple Choice section at 50% and the Free Response section at 50% of the total exam.
Percentage Conversion: The raw score from each section is converted into a percentage of the total possible points for that section.
MCQ Percentage = (Multiple Choice Raw Score / Total Possible Multiple Choice Points) * 100
FRQ Percentage = (Free Response Raw Score / Total Possible Free Response Points) * 100
Weighted Score: The percentages are then weighted.
Weighted MCQ Score = MCQ Percentage * 0.50
Weighted FRQ Score = FRQ Percentage * 0.50
Composite Score: These weighted scores are added together to form a composite score, which is then converted to the 1-5 AP scale. The exact conversion table is proprietary to the College Board, but this calculator uses a widely accepted approximation.
Interpreting the AP Score Scale:
5: Extremely well qualified
4: Well qualified
3: Qualified
2: Possibly qualified
1: No recommendation
Use this calculator as a tool to gauge your potential performance and identify areas where you might need further review. Remember that actual scores are determined by the College Board.
