AP Exam Score Predictor
Predict your AP exam score (1-5) from practice test performance.
About this calculator
The College Board does not publish a single universal formula for converting raw section scores into the final 1-5 AP score -- the actual composite-score cutoffs are set separately for each subject and each exam year through a standard-setting process, and aren't announced until after that year's exams are scored. This calculator uses a simplified, generic model instead: it weights your Multiple Choice percentage and Free Response percentage by MC Section Weight to get a single Composite Score, then maps that composite to a 1-5 Predicted AP Score using cutoffs calibrated to the conversion charts College Board has published for released exams -- roughly 65% for a 5, 53% for a 4, 42% for a 3 and 34% for a 2, which is close to where AP Calculus AB and AP Physics 1 have landed.
Treat the Predicted AP Score as a rough planning estimate: the real cutoffs are set separately for each subject and each exam year and can sit several points either side of these. Raising either your MC Questions Correct or Free Response Score always raises Composite Score and, with it, the Predicted AP Score can only stay the same or improve, never get worse.

How to Use This Calculator
- Enter MC Questions Correct and MC Questions Total from a recent practice exam or released AP test.
- Enter your Free Response Score (%) — estimate this from rubric scoring or your teacher's feedback.
- Set MC Section Weight (%) to match your specific AP subject (most subjects are 50% MC / 50% FR; check College Board guidelines).
- The calculator shows your Predicted AP Score from 1 to 5 and Composite Score percentage.
- Review College Credit Likelihood to understand which score thresholds most colleges accept for credit.
- Use Points to Next Score to determine how much improvement is needed to reach the next score level.

Frequently Asked Questions
Why doesn't this match the exact AP score I actually received?
The College Board sets composite-score cutoffs separately for each subject and each exam year through its own standard-setting process, and those exact cutoffs aren't published in advance. This calculator uses simplified, generic cutoffs as a planning estimate -- your actual subject's real cutoffs can be higher or lower.
What should I set MC Section Weight to?
It varies by AP subject -- many exams split roughly 50/50 between multiple choice and free response, but some weight one section more heavily. Check your specific exam's published section weighting from the College Board or your teacher, and adjust the default 50% if your subject differs.
Can Predicted AP Score go down if I improve my Free Response Score?
No. Composite Score is a weighted average of your MC and Free Response percentages, and raising either one while holding the other fixed can only raise or hold steady the composite -- never lower it. Predicted AP Score moves the same way, since it's derived directly from Composite Score.
What does Points to Next Score mean?
It's the gap between your current Composite Score and the next score threshold up -- for example, if you're at a composite of 49% and the next cutoff is 53%, Points to Next Score shows 4. It's a rough target for how much your composite would need to improve to reach the next predicted score level. If you're already predicted a 5 it shows "At the top score (5)", since there is no higher band to reach.
