AP Score Calculator
Enter your practice scores by section to estimate a composite result and likely AP score range.
Practice score boundaries
These broad defaults are editable because College Board does not publish one permanent percentage conversion for every subject and exam version.
Section weights and starting point totals follow the linked College Board format. You can edit points possible to match a particular practice test. The 1–5 result uses broad practice-score bands, not an unpublished official cut score, so treat the range as more useful than a single number.
College Board AP Biology exam formatHow the AP score predictor works
The calculator converts each practice section into a percentage, applies the selected exam's section weight, and combines the sections into a practice composite.
The predicted 1–5 score uses broad readiness bands. The range is intentionally more cautious than websites that present an unofficial raw-score cutoff as exact.
Why AP cut scores can differ
College Board develops multiple versions of each exam and uses score-setting research and equating to preserve comparable standards. That means the same raw percentage is not guaranteed to produce the same AP score across every subject and administration.

Common questions
How accurate is an AP score calculator?
It is a practice estimate. Section weights can follow the official exam format, but College Board uses statistical score-setting and exam equating rather than publishing one permanent raw-score conversion.
What AP score is passing?
AP scores run from 1 to 5. A 3 is described as qualified, but every college sets its own credit and placement policy.
What percentage do I need for a 5?
There is no universal official percentage for every AP subject or exam version. This calculator uses a broad 75% practice benchmark and shows a range instead of claiming an exact cut score.
Does the calculator use the correct section weights?
Yes for the supported AP exams. The selected exam's section weights and structure come from its current College Board exam page.
