First of all, the purpose of training is different. High school is a basic education, and more is to lay the foundation for students to receive a higher level of education. University is a social-oriented professional education, which not only improves students' professional knowledge and skills, but also promotes their all-round development, in order to cultivate high-quality professionals who can be independent and contribute to social and scientific and technological progress. High schools often talk about heroes by their course scores, while universities talk about their level by their comprehensive evaluation ability.

Secondly, the training concept is different. High schools focus on basic knowledge and strive to make students "learn". When cultivating "learning" students, universities emphasize that students should not only "learn", but more importantly, "learn". Finally, the forms of education are different. Middle schools are closed education, while universities are open education. The content of middle school education is closed, and each school organizes teaching according to the teaching content and requirements stipulated in the syllabus. The university stage is open education. In addition to teachers imparting knowledge, it is more important for students to actively choose their own inquiry learning. There is such a metaphor. In middle school, students passively absorb nutrition and get a "package" of services. The school distributes "parcels" on time. Almost all learning activities are arranged by the school, and students do whatever the teacher asks them to do. The level of schools and teachers determines the quality of the "set meal". As long as students eat well, there is no need to think about how to make the "set meal". In college, students put more emphasis on autonomous learning, and they should think about what they need, what is helpful to their self-growth and how to learn and improve their abilities. This is more like a "buffet", or even a "buffet" that only provides "raw and processed ingredients". Students must know their own needs and choose their own meals in order to make nutritious meals. If students don't think about it and try to use the educational resources of colleges and universities, these resources will not be automatically allocated. Then no matter how high-quality universities and high-quality educational resources are, it doesn't mean anything to him. Therefore, only those students who have future plans and goals and can make full and effective use of school educational resources to improve themselves can have good development in universities. One of the important purposes for candidates to choose high-level universities is to choose high-quality educational resources. The choice is used after entering school, not on the bookshelf.
