In 1901, the course of study at City College went through a series of further changes. The most significant was the reduction of the five-year course of study to four years; though students who entered prior to 1900 were allowed to complete the five-year course. The new course, like the course it replaced, allowed graduates to be admitted to Johns Hopkins University without examination, and provided students with greater flexibility. Instead of requiring students to complete the same set of courses, it allowed students to choose their courses, as long as they completed 150 credits.
