Because high school is different from university, university is mainly the responsibility of guiding teachers, not as high as the responsibility of class teachers. The most important role of a class teacher is to understand each student's learning situation, improve their expectations of academic performance, and communicate with recognized teachers in the class. It has the deepest effect on comprehensively understanding students' group photos, but it is different in college. Tour guides are basically not responsible for students' learning, because in college, students, you are an adult, you can be responsible for some of your actions, and you don't need tour guides to study with pig hands anymore, because if they are still students like high school teachers in college, then this student will go to college for nothing, if tour guides have to worry so much about them from high school teachers. There are at most 50 or 60 students in high school, but a college tutor basically has to take several classes and basically needs to take care of about 300 students. If he went to high school, the guide would have been exhausted, and students should not be in charge like high school. Students should learn the ability to take care of themselves independently after they go to college. If they can't learn, then his university will basically be abolished. In the university, to exercise the independent ability of studying now, it requires them to learn to manage their own study and life, and let them urge themselves to study, instead of letting them learn from party member in the university through teachers. There's basically nothing to worry about. It doesn't matter if you are admitted to graduate school or not, and it doesn't matter if you are admitted to other schools, because there is no problem of enrollment rate in universities, and in high schools, enrollment rate is very important to the head teacher of a class, so this is the difference!
