AP exams, or Advanced Placement exams, are standardized tests administered by the College Board. They allow high school students to earn college credit or advanced placement in college courses based on their performance. These exams cover a variety of subjects, including Mathematics, Science, History, and Languages. Students typically take AP courses during their junior or senior years of high school to prepare for these exams. Scoring well on an AP exam can help students save on college tuition and demonstrate their readiness for college-level work. Each exam is scored on a scale of 1 to 5, with 3 or higher often considered passing.
