1, high school teachers like writing on the blackboard, and university teachers like using PPT. (Not absolutely, because many high school teachers also use PPT)

There is a lot of homework after class in high school. When the teacher left his homework, he was quite bold, and he finished it in a few pages. University teachers basically only have a few exercises in the textbook, the first few questions in the first few pages and the first few questions in the first few pages.

You can ask questions at any time in high school, but only in recess and question-and-answer class in university (our university math teacher will teach many classes, and each class will have a math question-and-answer class every week. The teacher will always be in the classroom, students can ask questions, and the dormitory is fine.

4, high school teachers basically only change papers, after all, a few quizzes a week, a big exam a month, homework and so on, check whether they have done it at most, and rarely change it, all of which are taught directly in class. University teachers will carefully correct their homework every time, and the wrong answers will not only be crossed out, but also the reasons for the mistakes will be indicated. If you write well, you get an "excellent", probably because the university teacher has a daughter who is still in primary school? Anyway, the answer is very popular, and sometimes if you don't get an "excellent", you will be inexplicably lost.

5. There is no focus at the end of high school, but the university will focus.
