Undergraduate education is sometimes called undergraduate education, which is different from junior college education or junior college education and postgraduate education. Most people have both bachelor's degree certificates and bachelor's degree certificates. A few people only have a bachelor's degree certificate but have not obtained a bachelor's degree certificate because the number of failed courses exceeds the standard.

Undergraduate course is the basic part of higher education, and students can get a "bachelor's degree" after graduation. The undergraduate course of higher education self-study examination is a professional type of self-study examination, which is generally consistent with the similar professional level of ordinary colleges and universities. This kind of specialty can be divided into subsection undergraduate course and comprehensive undergraduate course (note: the concepts of subsection undergraduate course and comprehensive undergraduate course are created by the author for the convenience of readers).

According to the different batches of college entrance examination, undergraduate courses are also divided into one, two (including public two and civil two) and three, but they all belong to the same level and level (that is, undergraduate education level). At the same time, undergraduate courses are divided into "key undergraduate colleges" and "ordinary undergraduate colleges". "Key undergraduate colleges" and "ordinary undergraduate colleges" only focus on differences, and there is no essential difference. The former focuses on theoretical research, while the latter focuses on theoretical practical application.

Different levels of undergraduate education (subordinates, provinces and cities), different undergraduate education systems and their nature (public and private), different tuition fees determined by the school-running system, and the similarities and differences between "one, two (including two public and two private) and three" graduation certificates and undergraduate colleges. So one university, two universities (including two public universities and two private universities) and three universities have the same bachelor's degree and diploma, but the emphasis is different. Key undergraduate universities (985,211university) emphasize theoretical research. Ordinary undergraduate universities include one ordinary university, two public universities, two private universities and three universities. That is, key undergraduate courses focus on research, while ordinary undergraduate courses focus on application.

The school has 1, 2, 3, but the students don't have 1, 2, 3. They are all undergraduate diplomas, with the same academic qualifications.
