The origin of AP courses: The AP program was launched by the Ford Foundation in 1951.

In 1955, the College Board took over the management and held the AP exam for the first time the following year. At that time, there were only 11 exam courses.

In 1958, the College Board invested a lot of manpower and financial resources in teacher training, and in the following 10 years, it vigorously trained teachers during the summer vacation.

In the 1960s and 1970s, the College Board worked hard to promote this expensive course to students from low-income families. It opened classes at a school in Virginia that trained African-American World War II veterans, and also opened classes in New York.

The city's public TV station broadcasts instructional videos of AP courses.

In the following twenty or thirty years, AP courses were continuously supplemented until the current 34 exam courses were formed.
