Undergraduates typically take four courses each quarter and twelve courses in an academic year and are required to complete at least twelve quarters on campus to graduate.

The comprehensive doctoral graduate program has high coexistence with undergraduate programs.
Document 5: The New Yorker: Brown's nearly six-year tenure attracted more controversy than Gottlieb's or even Shawn's, thanks to her high profile (Shawn, by contrast, had been an extremely shy, introverted figure) and the changes which she made to a magazine that had retained a similar look and feel for the previous half-century. She introduced color to the editorial pages (several years before "The New York Times") and photography, with less type on each page and a generally more modern layout. More substantively, she increased the coverage of current events and hot topics such as celebrities and business tycoons, and placed short pieces throughout "Goings on About Town", including a racy column about nightlife in Manhattan. A new letters-to-the-editor page and the addition of authors' bylines to their "Talk of the Town" pieces had the effect of making the magazine more personal. The current editor of "The New Yorker" is David Remnick, who succeeded Brown in July 1998.

Document 14: To Kill a Mockingbird: Lee's childhood friend, author Truman Capote, wrote on the dust jacket of the first edition, "Someone rare has written this very fine first novel: a writer with the liveliest sense of life, and the warmest, most authentic sense of humor. A touching book; and so funny, so likeable." This comment has been construed to suggest that Capote wrote the book or edited it heavily. In 2003, a Tuscaloosa newspaper quoted Capote's biological father, Archulus Persons, as claiming that Capote had written "almost all" of the book. In 2006, a Capote letter was donated to Monroeville's literary heritage museum; in a letter to a neighbor in Monroeville in 1959, Capote mentioned that Lee was writing a book that was to be published soon. Extensive notes between Lee and her editor at Lippincott also refute the rumor of Capote's authorship. Lee's older sister, Alice, responded to the rumor, saying: "That's the biggest lie ever told."

The "Encyclopedia" was compiled and published some time between "God Emperor of Dune" (1981) and "Heretics of Dune" (1984), and Herbert "read large portions of "God Emperor of Dune", then in the final stages, to McNelly during the compiling of the volume so that McNelly could keep abreast of developments." However, Herbert did not hesitate to render it erroneous through later developments in his "Dune" series. Herbert himself wrote the foreword for the "Encyclopedia" (dated November 1983), which noted:
