First of all, there are many unqualified standards. If a college student is dismissed because he is unqualified, it depends on which one he is unqualified. If it is a trivial matter, I don't think it is correct to expel him from school. If the bottom line is involved, then I think the school is doing the right thing.
The first criterion is that college students are not qualified because of their poor academic performance. If this is the reason, I don't think it is appropriate for the school to expel college students. Every college student's own situation is different. Some students study well and are self-disciplined. Therefore, compared with those students who have poor academic performance and are not self-disciplined, there is definitely a gap. It is not good to expel students just because of poor academic performance.
The second criterion is that college students violate school rules. If a college student has serious bad behavior, it will have a great impact on the school, so I think it is the right choice for the school to expel this student. But if the student's mistake is not so big, I think the school can still give this student a chance. After all, it is not easy to study hard in the cold window of 12 and be admitted to the university. It depends on whether the college student's behavior is serious or not.
The third criterion is that college students have done something illegal. If a college student's behavior involves the bottom line, such as breaking the law, then I think it is reasonable to expel him. As a college student and an adult, I should be responsible for my actions and should not be so reckless. If you break the law on impulse, you should be responsible for your actions. Expelling from school is a natural result, and I agree with it.
Therefore, for the phenomenon of expelling unqualified college students from schools, I think it depends on these three unqualified standards and which one the college student violated.
