AP classes, or Advanced Placement classes, are college-level courses offered to high school students in subjects such as English, history, math, science, languages, and more. These courses are designed to give students the experience of an introductory college class while still in high school

. Key features of AP classes include:

• They cover rigorous, college-level curricula developed by the College Board and taught by high school teachers

• At the end of the course, students take an AP exam scored on a scale from 1 to 5. Scores of 3 or higher often qualify for college credit or advanced placement in college courses, though exact credit policies vary by institution

• AP exams typically last 2-3 hours and include multiple-choice and free-response questions

• There are currently about 38 to 40 AP courses available in various subjects such as biology, calculus, history, computer science, languages, and more

Taking AP classes and performing well on the exams can strengthen college applications and potentially reduce college course loads and tuition costs by earning college credit in advance

. In summary, AP classes help high school students prepare for college-level work and may allow them to earn college credit before graduating high school
