How the estimate works
AP Calculus AB and BC use a multiple-choice section and a free-response section. This calculator treats MCQ as 50% of the composite estimate and FRQ as 50%, then maps the result to an unofficial 1-5 range.
For 2026 FRQs, estimate each question out of 9 points after checking the released question set and any teacher review notes. Do not treat this as an official score report.
