The greatest difference between undergraduate and graduate school is the singular course of focus in graduate school. Undergraduate school focuses on preparing students with a general understanding of multiple subjects in addition to a specific course of study of their choice. Specific courses of study are called "majors" at the undergraduate level. Graduate students focus solely on a specific course of study. The study of a singular subject requires in-depth research.
Undergraduate and graduate schools offer different degree programs. Students obtain either a Bachelor of Science or a Bachelor of Arts upon completion of undergraduate school. Graduate students obtain either a master's degree or a doctorate degree. However, graduate students must be admitted to either master's or doctoral degree programs to obtain the respective degrees.
The minimum time commitment to obtain an undergraduate degree is four years. Some students obtain their undergraduate degree in shorter time by taking summer classes or additional classes during each semester. The time commitment for graduate school is contingent on the degree sought. Master's degree programs can last for one to three years depending on the subject studied. Doctoral degree programs last for three to five years.
Graduate school requires a level of intellectual application that is more rigorous and stringent than undergraduate study. Many graduate programs expect students to attribute some personal or professional experience to their deepening understanding of the subject studied. Graduate students also direct their own course of study under supervision of a professor. Self-guided study requires a higher level of self-discipline than in undergraduate school where professors require frequent assignment submissions in order to guide students through the learning process.
