As the importance of higher education increased in the early 20th century, the High School's priorities shifted to preparing students for college. In 1927, only one year before the school moved from its home at Howard and Centre Streets for 53 years to the magnificent stone "Castle on the Hill" on "Collegian Hill", the academic program was further changed, when the City College divided its curriculum into two tracks: the standard college preparatory program, or "'B' Course", and a more rigorous stiff "Advanced College Prep" curriculum, the famed "'A' Course" of study focusing on humanities, social studies, liberal arts and the Classics. (also available in the mathematics/science/technology fields in a more structured form with little options/electives at "Poly" and at Western and Eastern High Schools for girls).
