How the Calc BC exam is scored

The 2027 AP Calculus BC exam is on Monday, May 10, 2027 (Session 1, usually morning), and AP scores come out in July.[7][8] AP Calculus BC uses exactly the same layout and weights as AB, but covers more content. It is also hybrid: Bluebook for multiple choice, paper booklets for free-response answers.[1] In hybrid exams you read everything in Bluebook but handwrite free-response answers in a paper booklet.[4]
