AP Calculus AB Score Calculator
Estimate your AP Grade based on Multiple Choice and FRQ performance.
How the AP Calculus AB Score is Calculated
The AP Calculus AB exam consists of two main sections: Section I (Multiple Choice) and Section II (Free Response). Each section accounts for 50% of your total score. To determine your final AP grade (1-5), the College Board uses a weighted composite score.
1. Section I: Multiple Choice (MC)
There are 45 multiple-choice questions. Your raw score is simply the number of questions answered correctly. There is no penalty for guessing. To balance the exam weighting, your raw MC score is multiplied by 1.2222 (often simplified as 1.2 in rough estimates) to reach a maximum of 54 points.
2. Section II: Free Response Questions (FRQ)
There are 6 FRQs, each worth 9 points. Your raw FRQ score is the sum of these points (maximum 54). Unlike the multiple-choice section, these points are used directly in the composite calculation without a multiplier.
3. The Composite Score
Your composite score is calculated as follows:
Composite Score = (MC Correct × 1.2222) + (FRQ Total Points)
The maximum possible composite score is 108. The College Board then maps this score to an AP Grade of 1, 2, 3, 4, or 5 based on that year's specific curve.
AP Calculus AB Score Cutoffs (Typical Range)
| AP Grade | Composite Score Range (Approx) | Performance Description |
|---|---|---|
| 5 | 68 – 108 | Extremely Well Qualified |
| 4 | 52 – 67 | Well Qualified |
| 3 | 41 – 51 | Qualified |
| 2 | 29 – 40 | Possibly Qualified |
| 1 | 0 – 28 | No Recommendation |
Score Calculation Example
If a student gets 32 questions correct on the Multiple Choice section and earns a total of 25 points across the 6 FRQs:
- MC Weighted Score: 32 × 1.2222 = 39.11
- FRQ Score: 25
- Composite Score: 39.11 + 25 = 64.11
- Estimated Grade: 4
This student would likely receive a 4, being very close to the cutoff for a 5. Using this calculator can help you identify where you need to improve to reach your target score.
