AP Calc AB Score Calculator

How It Works

The AP Calculus AB exam consists of two main sections. Section I includes 45 multiple choice questions split across two parts: Part A (30 questions, no calculator) and Part B (15 questions, calculator allowed). Section II contains 6 free-response questions, each typically scored out of 9 points, totaling 54 points.

By default, this calculator uses equal weighting: MCQ 50% and FRQ 50%. These weights reflect typical exam structures, though you can customize them in the Advanced Settings panel to match specific practice exams or teacher-provided curves.

The formula calculates each section's percentage (earned ÷ total), applies the weights, sums them to get a weighted raw percentage, then maps that to the 1–5 score bands. The default bands are approximate and not official—exact AP curves vary each year based on overall student performance.

Inputs Explained

• MCQ Correct and Total: Enter the number of multiple choice questions you answered correctly out of the total (typically 45). This section tests your understanding of calculus concepts, computational skills, and problem-solving across both no-calculator and calculator portions.
• FRQ Questions 1-6: Input your rubric points earned (0–9) for each free-response question. These questions require detailed work showing your understanding of limits, derivatives, integrals, and applications of calculus.
• FRQ Total: This is automatically calculated as the sum of all your FRQ points. The default maximum is 54 points (6 questions × 9 points each).
• Advanced Settings: Adjust section weights (must sum to 100%) or customize the score band thresholds to match a specific curve if your teacher has provided one.

Example Calculation

Let's walk through a sample calculation with these scores:

• MCQ: 31 out of 45 → 31 ÷ 45 ≈ 68.9%
• FRQs: 7 + 6 + 6 + 5 + 4 + 7 = 35 out of 54 → 35 ÷ 54 ≈ 64.8%

Using the default weights (MCQ 50%, FRQ 50%), the weighted raw percentage is:

(0.689 × 0.50) + (0.648 × 0.50) ≈ 0.668 = 66.8%

With the default curve, 66.8% falls in the 60–74% band, yielding an estimated score of 3.

Tips & Notes

• Curves Change by Year: College Board adjusts the curve each year based on overall student performance. Treat this calculator as a study guide, not a prediction of your actual score.
• FRQ Points Matter: Notice how a few FRQ points can swing your estimate significantly. Practice showing all steps and justifying your work to maximize partial credit.
• Match Teacher Curves: If your teacher shares a curve from past exams, edit the score bands in Advanced Settings so your results mirror that specific curve.
• Balance Calculator and No-Calculator Skills: Practice both non-calculator and calculator sections to build speed and accuracy across different problem types.
• Focus on Conceptual Understanding: AP Calc AB rewards deep understanding of fundamental calculus concepts over memorization. Use this calculator to identify areas needing more review.
