Undergraduate degree is the basic part of higher education, which is generally carried out by universities or colleges. Few higher vocational colleges carry out applied undergraduate education. Undergraduate education is more important than general education of theoretical majors, and applied undergraduate education is more important than applied professional education and practical skills education. Students can generally get undergraduate diploma and bachelor's degree certificate after normal graduation.

The first batch of undergraduate colleges (referred to as "One") are national key universities with good students. Admission to a middle school, A and B institutions have no influence on each other, but the same minimum control line is implemented. The enrollment is about 22% for liberal arts and 35% for science. One is a key undergraduate course.

The second batch of undergraduate courses (referred to as "two undergraduate courses" for short) are ordinary undergraduate colleges, in which Class A and Class B implement the same two-line admission. The enrollment is about 78% for liberal arts and 65% for science. The second is an ordinary undergraduate course.

The third batch of undergraduate courses (referred to as "three books" for short) are private colleges and universities established in recent years, which belong to colleges with high fees. The number of people admitted in the first, second and third batches is about 30% for liberal arts and about 25% for science. Three books are more common.
