An estimate — because the real cut scores are secret
The College Board does not publish the raw-score cutoffs for a 5, 4 or 3; it sets them each year from that year's results. What calculators like this one can do is rebuild the system from the outside: the section weights are official (they are in each course framework), and the cut points are the estimates published by established prep sources from years of released data. Treat the result as a well-informed estimate, not a promise — a hard year's exam can move a boundary by several points.
Each subject's sections and weights follow its College Board framework: AP Biology, for example, is 60 multiple-choice questions (50%) plus six free-response questions worth 34 points — two long at 9 points, four short at 4 (50%).
Worked example
In AP Biology, a student with 36 of 60 multiple-choice correct and 14 of 34 free-response points earns a composite of 30.0 + 20.6 = 50.6% — squarely in the estimated band for a 3 (the same worked example published by AP score references puts that performance at a 3). The bands move by subject: Calculus AB's 5 has historically needed only ~68% of the composite, while English Language's takes ~78%.
How to use this calculator
- Pick your subject — the form rebuilds itself with that exam's real sections.
- Enter multiple-choice correct answers (no penalty for wrong answers, so never leave blanks on the real exam).
- Enter your free-response points per question — in practice tests, score yourself against the official rubrics, strictly.
- Read the estimated score and the gap to the next band: it tells you whether your remaining study time belongs in MCQ speed or FRQ points.
Unofficial estimate. Cut scores vary by year and exam form and are never published in advance. This tool is for study planning — colleges see only the official score the College Board reports.
