Not exactly. Now, the teacher asks the students to sign their names. For example, a teacher said, "I can sign for so many people, so please sign for me." If there is a problem, TA is also responsible, because that is TA's signature. Besides, this kind of cheating is nothing more than to increase the employment rate and trick little boys and girls into their schools. It doesn't matter if it is illegal, but it is morally unacceptable. What answer do you want? Just asking.
