Advanced Placement courses, often abbreviated as AP courses, are college-level classes offered in high school. They allow students to study subjects in greater depth and prepare for the AP exams, which can earn them college credit if they score well. These courses cover a variety of subjects, including math, science, history, and languages. Taking AP courses can enhance a student's academic profile when applying to colleges. They demonstrate a willingness to challenge oneself and can lead to advanced placement in college courses, potentially saving time and money on tuition.
