It is necessary in most cases, because the evaluation teacher is in this major. If you study science and technology and publish a particularly good social survey paper, this paper is submitted by this major, but the teacher can't understand it and can't judge the value. You can participate in the evaluation, but you can't get high marks. In this case, you can also try to apply for scholarships from other institutions, and they will understand. But if outsiders come to grab places, no one will pay attention unless it is a famous achievement of the whole school.
