The Advanced Placement Exams exists to give students college credit while still in high school. This credit helps students enter into college without having to take the course over again and helps speed along with degree progression while also saving on tuition fees. Students must scale at least a three out of five in order to obtain credit for the course. Policies for credits vary by college from college to college, so it’s best to score as high as possible in order for the class to be accepted by your chosen school.
