Preparing for the AP Calculus AB or BC exam can be one of the most stressful experiences of a high school student's academic career. Between derivatives, integrals, and the dreaded Taylor series, it's easy to lose track of how your performance translates into that final 1-5 score. Use our calculator below to estimate your score based on current College Board curves.

How the AP Calculus Score is Calculated
The AP Calculus exam (both AB and BC) consists of two main sections that are weighted equally at 50% each. However, the raw points don't match up exactly, so a multiplier is applied to the Multiple Choice section.
- Section I: Multiple Choice: 45 questions. Your raw score (number correct) is multiplied by 1.2 to give a maximum weighted score of 54.
- Section II: Free Response: 6 questions, each worth 9 points. This section has a maximum raw score of 54.
- Composite Score: The weighted MC score and the raw FRQ score are added together for a maximum possible composite score of 108.
The "Curve" and Score Cutoffs
One of the most encouraging things about the AP Calculus exam is the generous curve. You do not need a 90% to get a 5. In fact, on many versions of the exam, scoring around a 65-70% of the total points is enough to secure the highest score.
While cutoffs change slightly every year based on the difficulty of the specific exam, here are the typical ranges for the composite score (out of 108):
- 5: 70 – 108
- 4: 55 – 69
- 3: 40 – 54
- 2: 30 – 39
- 1: 0 – 29
Tips for Maximizing Your Score
1. Don't Leave Multiple Choice Blank
There is no penalty for guessing on the AP Calculus exam. If you are stuck on a problem, eliminate the obviously wrong answers and make an educated guess. Never leave a bubble empty.
2. Show All Your Work on FRQs
In the Free Response section, the "answer" is often only worth 1 out of the 9 points. Most of the points come from the setup, the application of theorems (like the Mean Value Theorem or Fundamental Theorem of Calculus), and the intermediate steps. Even if your final calculation is wrong, you can still earn 7 or 8 points if your logic is sound.
3. Use Your Calculator Wisely
Remember that only two of the six FRQs allow a graphing calculator. Practice using your calculator for finding intersections, calculating numerical derivatives, and evaluating definite integrals so you don't waste precious time during the test.
