1. Every batch of college entrance examination students need to fill in the schools and majors that need to collect volunteers in previous years. Due to various reasons, there are fewer candidates in these voluntary schools and majors, and they may not be able to recruit enough people in regular volunteering, so there is a greater chance to apply for such schools and majors.

2. The pressure line students can also give up the pressure line batch and fill in the next batch of volunteers, so that they can choose a better school and major. Although the school level has been lowered, it can be admitted to an ideal major.
