Students who take AP courses get a head start on college.
Students who take the AP exam at the end of the course demonstrate to the colleges and universities that they are ready for college - in turn - allowing them to gain admission, college credit and placement into advanced courses.
Even if it is not the goal of the student to earn credit or placement, at the very least they will:
Be a step ahead
Stand out in the admissions process
Experience a college-level exam
Be more likely to earn academic scholarships and awards
