This total is compared to a composite-score scale for that year's exam and converted into an AP score of 1 to 5.įor the Calculus BC exam, an AB sub-score is included in the score report to reflect their proficiency in the fundamental topics of introductory calculus. The raw score is then added to the adjusted multiple choice score to receive a composite score. The free response section is hand-graded by hundreds of educators each June. This total is multiplied by 1.2 to calculate the adjusted multiple-choice score. The multiple choice section is scored by computer, with a correct answer receiving 1 point, with omitted and incorrect answers not affecting the raw score. However, students may continue to work on Section II Part A during the entire Free-Response time, although without a calculator during the later two thirds. Students are required to put away their calculators after 30 minutes have passed during the Free-Response section, and only at that point may begin Section II Part B. The two parts of the multiple choice section are timed and taken independently. They are usually administered on a Tuesday morning in May. Both exams are three hours and fifteen minutes long, comprising a total of 45 multiple choice questions and six free response questions. The structures of the AB and BC exams are identical. However, they do not count the AB sub-score piece of the BC exam. The AP awards given by College Board count both exams. Some schools do this, though many others only require precalculus as a prerequisite for Calculus BC. The College Board intentionally schedules the AP Calculus AB exam at the same time as the AP Calculus BC exam to make it impossible for a student to take both tests in the same academic year, though the College Board does not make Calculus AB a prerequisite class for Calculus BC. A possible explanation for this is that students who take AP Calculus BC are more prepared and advanced in math, leading to its higher pass rate compared to AP Calculus AB. It is worth mentioning that the pass rate (score of 3 or higher) of AP Calculus BC is higher than AP Calculus AB.
