As the 2012 school year begins to wind down, many students across the country are diligently preparing for Advanced Placement exams in 34 different subject areas. AP courses are designed to help high school students acquire the skills and study habits essential for success in college. With test dates running from May 7 through May 25, AP students are poised to hit the ground running when beginning their post-secondary careers, should they earn a score high enough to gain them college credit.
In keeping with the testing season, we are very excited to launch an infographic that highlights the progress made within AP curricula over the past decade. Our graphic, “The Rise of the AP,” shares information and statistics from the College Board’s 8th Annual “AP Report to the Nation.”
