What it answers that a model cannot answer alone

A language model answers from training data that is months old and does arithmetic from memory. This server returns the current figure with its source. In the words of its README, it knows these things that your model does not.

  1. The May 2026 results. College Board posted the 2026 AP Score Distributions after the 2026 exams, which is newer than most model training data. For example, 46% of AP Calculus BC students scored a 5 in 2026, and AP Biology’s pass rate was 71%.
  2. Exact 2024 and 2025 counts. 287,232 students took AP Biology in May 2025 and 70.4% scored 3 or higher, with a mean of 3.24. All 49 rows per year (40 exams, 3 subscores, 6 Standard Group language rows) pass a check that counts add to the printed total and 5 + 4 + 3 equals the printed 3 or higher count.
  3. Which cut charts exist. College Board does not publish cut scores for live exams. The estimator uses only the 7 conversion charts College Board printed in its practice exams (Calculus AB 2012, Biology 2013, Statistics 2012, World History 2013, Psychology 2012, Macroeconomics 2012, Microeconomics 2012) and refuses every other exam rather than invent a cut.
