Universities are divided into junior colleges and undergraduate courses. This concept should not be confused. Undergraduate course is generally called a university, which is often called "upgrading from junior college to undergraduate course". It is the connection between the two and an opportunity for junior college students. Because of the different goals of cultivating talents, disciplines are divided into junior colleges and undergraduate courses. Specialized courses cultivate skills and technical talents. Although there is no shortage of skills for undergraduates, their original intention is to cultivate research-oriented talents. After all, if we want the times to progress, we must innovate and develop. In short, specialized courses make technology more complete, and undergraduate courses find a new way out. The so-called "specialization in technical fields", in order to better adapt to the cultivation of talents, the classification of undergraduate courses can also be said-teaching students in accordance with their aptitude.
