1. College students need to attend classes because of their academic requirements, which is a kind of ability improvement for students themselves. Some students are lazy and can't study, so they find someone to brush their lessons instead. If you want to give lessons to others, this behavior is not recognized. Because it doesn't mean anything to you or the students.

2. Brushing classes for college students will not lead to jail, but if caught by the school, it will have an impact on students' studies or future development. People who brush classes will also be affected, so it is best not to brush classes for students.

So, if you meet some students who want to brush their classes, try to persuade them to study hard, because they will always suffer.
