Understanding Your AP Calculus AB Score Calculation
Your final AP Calculus AB score (from 1 to 5) is determined by calculating a "Composite Score" based on both sections of the exam. The exam is split evenly in weight: 50% for the Multiple Choice (MC) section and 50% for the Free Response Questions (FRQ). Because there are fewer MC questions than FRQ points, a multiplier is applied to the MC section to balance the exam.
- Multiple Choice = 45 questions max. Each correct answer is multiplied by 1.2 (Max = 54 points).
- Free Response = 6 questions max. Each is worth up to 9 points (Max = 54 points).
- Maximum Composite = 54 (MC) + 54 (FRQ) = 108 total points.
Note: There is no penalty for guessing on the AP Exam. Only correct answers count towards your composite score.
| AP Score | Composite Score Range | Interpretation |
|---|---|---|
| 5 | 68 – 108 points | Extremely Well Qualified (Usually earns college credit) |
| 4 | 54 – 67 points | Well Qualified (Often earns college credit) |
| 3 | 42 – 53 points | Qualified (Sometimes earns college credit) |
| 2 | 32 – 41 points | Possibly Qualified (Rarely earns credit) |
| 1 | 0 – 31 points | No Recommendation |
Frequently Asked Questions
Is the AP Calculus AB scoring curve the same every year?
No. The College Board slightly adjusts the required composite scores (the "cutoffs") every year based on the overall difficulty of the exam to ensure standardized results. However, the cutoffs generally only fluctuate by a few points year-over-year. The table above provides a highly reliable historical average.
Do I need to pass both sections to get a 5?
No, your AP score is entirely based on your total Composite Score out of 108. You could theoretically perform poorly on the Free Response but completely ace the Multiple Choice and still achieve a high overall score, as long as the combined total meets the cutoff for a 5 (usually around 68 points).
How are the Free Response Questions (FRQs) graded?
Each of the 6 FRQs is graded on a 9-point scale by AP Readers (usually high school teachers or college professors). Points are awarded for setting up the correct calculus equations, showing logical mathematical steps, and arriving at the correct final answer with proper units.
