First, I have been single for four years. After entering the university, the students got rid of the supervision of teachers and parents. I believe many students want to take this opportunity to experience the feeling of love, and the "underground" love in high school can also become "above ground". But the terrible thing is that some students have been single for four years in college, which is something that bothers many college students.

The types of universities in China are divided into comprehensive universities, science and engineering universities, liberal arts universities and medical universities. Different types of schools have different ratios of male to female, which will have a certain impact on students' finding objects.

There are also some students who like to stay in the dormitory during college and will not take the initiative to participate in various activities, which limits their social circle to some extent. There is also a high probability that such students will remain single. Many people say that love in college is very simple, and it is a wonderful thing to talk about love in college, so being single for four years is a pity for many college students.

Second, when you fail the exam. For high school students, they can not only pass every exam, but also exceed the passing score by dozens of points. However, after entering the university, students seem to have lost the state of studying in high school. Students basically start reviewing two weeks or a month before the final exam, and even some subjects just review suddenly two days before the exam.

As a result, many students embarked on the road of no return. After each final exam, students are anxiously waiting for the results announced by the educational administration system. When they see that their scores have not reached 60, they will be very upset, and they should also prepare for make-up exams or make up classes after school starts.

However, since they all worked hard to get into college, I believe that the students' learning ability is not bad, and it is still a very small phenomenon that they fail to get into college.

But the failure rate of some subjects is very high, such as advanced mathematics, linear algebra and probability theory. These subjects are difficult and have a high failure rate. I suggest that students must be more careful when studying these subjects.

Third, when the class is suddenly asked questions. Even if there are few courses originally arranged in the university, few students will listen carefully during class hours, and basically they will play with their mobile phones in class. Even if some students are willing to listen to the teacher carefully from the beginning, they will unconsciously pick up their mobile phones during the class.

If a classmate who plays mobile phone seriously is suddenly asked by the teacher, it is very likely that the first reaction when he stands up is to ask the teacher what the question is. This is embarrassing, but it is very common in college classes.
