First of all, the level of higher education is different. Both undergraduate and graduate students belong to the category of higher education, but the specific academic level is different. Postgraduate education is higher than undergraduate education.
Second, the enrollment methods are different. Undergraduate education can be achieved through college entrance examination, self-study examination, adult college entrance examination, online education, and higher vocational education.
Third, the cultivation process is different. Except for the special classes in top universities such as Tsinghua and Peking University, undergraduates generally don't deserve special tutors, and the graduation standards don't require high papers. Each graduate student is equipped with a tutor and receives the "one-on-one" guidance from the teacher. Graduation standards have extremely high requirements for dissertations.
Fourth, the degree of social recognition is different. For graduates of the same major, master students are more favored by employers than undergraduates, and have more advantages in employment and recruitment, and the average salary level is also higher than that of undergraduates.
