Estimate your AP Statistics composite score
Use the current 2027 AP Statistics format: 42 multiple-choice questions worth 50% and four free-response questions worth 50%.
AP Statistics exam format for 2027
The AP Statistics exam is 3 hours long. Section I has 42 multiple-choice questions in 90 minutes and counts for 50% of the exam score. Section II has four free-response questions in 90 minutes and also counts for 50%.
Each free-response question is scored on a 10-point scale and contributes 12.5% of the total exam score.
How the AP Stats grade calculator works
The calculator converts your multiple-choice score to a percentage and applies the 50% section weight. It then adds the four free-response scores, converts the total out of 40 into a percentage and applies the other 50%.
Composite = (MCQ % × 0.50) + (FRQ % × 0.50)
This gives a weighted practice composite percentage. It is not an official College Board 1–5 score conversion.
What changed for the 2027 AP Statistics exam?
The revised exam increases the multiple-choice section from 40 to 42 questions and reduces the free-response section from 6 questions to 4. Each new free-response question is worth 10 points. The exam is also fully digital in Bluebook for 2027.
