First of all, it depends on what form you are promoted from junior college to undergraduate course. Generally speaking, there are four types of undergraduate courses:

1, colleges and universities. Generally speaking, college students in ordinary colleges and universities take exams before graduation, usually by upgrading to higher education or taking the unified exams in other schools. After graduation, they go directly to undergraduate study, and finally get a diploma, which is ordinary higher education.

2. Enter the college entrance examination. To apply for adult colleges and universities, the school can choose independently in the enrollment plan, whether it is in this province or other provinces, as long as all majors can apply, and the specific choice of majors needs to be decided according to the professional difficulty and personal interest.

3. Self-taught college entrance examination. Although there are many self-taught schools and majors, there are too many exam subjects. Some self-taught undergraduates need to take 10, about 20 courses, and some even exceed 30 courses, so self-taught undergraduates are the most difficult way to upgrade to undergraduate courses.

4. Distance Education College. Distance education can educate more than 60 certified colleges and universities, and the majors can be chosen independently among the existing majors. What major to choose depends on the difficulty of the major and personal interest.
