How to Score a 5 on AP Calculus AB and BC: College Board Curves, FRQ Rubrics, and Subscore Strategy
To earn a score of 5 on the AP Calculus AB or BC exam, students must achieve a total composite score of at least 68 out of 108 points (~63%) on AB, or 65 out of 108 points (~60%) on BC. Scoring is balanced equally between Section I (45 MCQs scaled by 1.2 to 54 composite points) and Section II (6 FRQs worth 9 points each = 54 composite points). Securing 34+ correct on the MCQ section leaves a required benchmark of only 28 out of 54 points on the FRQs.
Key Takeaway Facts
- Section I and Section II carry equal 50% weight (54 composite points each) toward the total 108-point maximum.
- The College Board applies zero penalty for incorrect multiple-choice answers; students should answer all 45 questions.
- On AP Calculus BC, students simultaneously earn an official AP Calculus AB Subscore based on roughly 60% of the exam.
- On Section II, intermediate calculus steps (limits, integral setups, derivatives) award partial credit even if arithmetic errors occur.
- A raw percentage of approximately 60% to 65% is historically sufficient to secure the highest score of 5.

Frequently Asked Questions
What is a good AB subscore on the BC exam?
An AB subscore of 4 or 5 is considered excellent and is accepted by the vast majority of universities for full Calculus I course credit, even if your overall BC score is a 3.
