Southern Californians were furious that their so-called "branch" provided only an inferior junior college program (mocked at the time by University of Southern California students as "the twig"), and continued to fight Northern Californians (specifically, Berkeley) for the right to three and then four years of instruction, culminating in bachelor's degrees. On December 11, 1923, the Board of Regents authorized a fourth year of instruction and transformed the Junior College into the College of Letters and Science, which awarded its first bachelor's degrees on June 12, 1925.
