AP Stats Grading Calculator Guide
This calculator estimates your final AP Statistics score (1–5) based on raw exam scores.
- Enter Multiple Choice scores: Input the number of correct and incorrect answers (out of 40). The calculator automatically applies the 1/4 point penalty for wrong answers.
- Enter Free-Response scores: For each of the 6 questions (Q1–Q6), enter a score between 0 and 4 (use 0.5 increments if needed). Q6 is the Investigative Task.
- Click "Calculate AP Score": The calculator computes a composite score (out of 100) using the formula: Composite = (MC Raw × 1.25) + (FR Raw × 3.125), where MC Raw = correct − (incorrect/4) and FR Raw = sum of all FR scores.
- View your result: The predicted AP score (1–5) appears as a badge, along with a detailed breakdown of MC raw, FR raw, and composite scores.
Note: All inputs must be within the specified ranges (MC: 0–40, FR: 0–4). Invalid entries will show red error messages.

Frequently Asked Questions
The composite score is calculated as: (Multiple Choice Raw Score × 1.25) + (Free-Response Raw Score × 3.125). The multiple choice raw score is the number correct minus one-fourth of the number incorrect. The free-response raw score is the sum of your scores on the six free-response questions (each scored 0-4).
The cutoffs used are: Composite ≥ 70 → AP Score 5; 60-69 → 4; 48-59 → 3; 35-47 → 2; below 35 → 1. These are approximate and may vary slightly by year.
This calculator provides an estimate only. Actual AP scores are determined by the College Board using a process that may adjust cutoffs slightly. Use this as a rough guide.
