College Board's Advanced Placement (AP) exams are standardized tests that allow high school students to earn college credit or advanced placement in college courses. These exams cover a variety of subjects, including AP Calculus, AP Biology, and AP English Literature, among others. Students typically take these exams at the end of their AP courses, which are designed to be more rigorous than standard high school classes. The exams are scored on a scale of 1 to 5, with a score of 3 or higher often considered passing. Many colleges and universities in the United States offer credit or advanced placement for students who achieve qualifying scores, making AP exams a valuable opportunity for students to enhance their academic profiles and potentially save on college tuition.
