AP Calculus AB/BC Scoring System:
From: | To: |
The AP Calculus exam uses a composite scoring system where your performance on both multiple-choice and free-response questions contributes to a final score on a 5-point scale. A score of 5 is the highest possible and indicates exceptional mastery of the subject matter.
The College Board uses a weighted formula to calculate your composite score:
Where:
Explanation: Your raw points from both sections are combined and converted to the 5-point AP scale using a statistical process called equating, which may vary slightly from year to year.
Details: While cutoffs vary annually based on exam difficulty, typically a composite score of approximately 63-75% (68-81 points out of 108) is needed to earn a 5. The exact cutoff is determined each year after all exams are scored.
Tips: Enter your estimated points from the multiple choice section (out of 54) and free response section (out of 54). Select whether you took the AB or BC exam. The calculator will estimate your likely AP score based on typical cutoffs.
Q1: Are the cutoffs the same every year?
A: No, cutoffs vary slightly each year based on overall exam performance and difficulty. The calculator provides estimates based on typical ranges.
Q2: What's the difference between AB and BC scoring?
A: While the scoring structure is similar, BC typically has slightly different cutoffs due to the more advanced content. BC students also receive an AB subscore.
Q3: How many points do I need for a 5?
A: Typically, you need approximately 68-81 points out of 108 (63-75%) to earn a 5, though this varies by year.
Q4: Is the multiple choice section weighted differently?
A: No, both sections contribute equally (50% each) to your final score.
Q5: When will I know my actual AP score?
A: AP scores are typically released in early July each year through your College Board account.
