Originally, the MBA degree was primarily designed as a two-year course of study for students who studied "the more rigorous subjects" of science, engineering, and the liberal arts while in college, but needed to understand business practices when they entered a career in commerce. As the MBA became prestigious, however, students who already had studied business at the undergraduate level also wanted the status of having an MBA degree. As a result, and because business is now by far the largest undergraduate major at many colleges, some MBA programs are primarily designed as one-year extensions of undergraduate business programs.
In general, a higher percentage of MBA students who majored in business tends to homogenize the backgrounds of the student body, whereas a lower percentage adds to the diversity of the MBA class.
