Have a question, found a bug, or want to suggest a new calculator? We'd love to hear from you. AP Score Lab is built and maintained by a small team that genuinely cares about helping AP students set realistic goals — feedback from actual users is how we improve.
If you notice that a calculator's scoring data doesn't match the latest College Board publications, please let us know. We strive to keep every calculator updated with the most recent official Course and Exam Description (CED) weights, scoring guidelines, and score distribution data. Each year after the May exam administration, we revisit all calculators in light of newly released distributions and rubric updates.
When reporting an error, please include: the calculator URL, the specific section (MCQ weight, FRQ rubric, cutoff band, etc.) you believe is incorrect, and a link to the College Board source you're referencing. The faster we can verify a correction, the faster we can push it live for every student using the tool.
We're actively expanding our calculator library. If you're studying for an AP exam that doesn't have a calculator yet (currently AP Art History, AP Music Theory, AP Latin, AP French, AP German, AP Japanese, AP Physics 2, AP Physics C: Mechanics, AP Physics C: E&M, AP Spanish Literature, AP Comparative Government, AP African American Studies, and AP Research), let us know — student demand is the biggest driver of which exam we tackle next.
We do not collect personal data, store your score inputs server-side, or share information with third parties. All score calculations happen locally in your browser. See our Privacy Policy for the full details.
