The AP Calculus exam is a standardized test administered by the College Board for high school students. It assesses students' understanding of calculus concepts, including limits, derivatives, and integrals. The exam is divided into two sections: multiple-choice questions and free-response questions, allowing students to demonstrate their problem-solving skills. Students can take either the AP Calculus AB or AP Calculus BC exam, depending on their coursework. Scoring well on the exam can earn students college credit or advanced placement in college calculus courses, making it a valuable opportunity for those pursuing higher education in math or science fields.
