Just finished the college entrance examination? I'm from Agricultural University, and my small classes are generally senior. Occasionally, there is a schoolmate, many of whom are members of the student union and some of whom are familiar with the teacher. They are responsible for leading freshmen to understand the campus, going through some admission procedures, filling out forms and so on. Organize freshmen to hold some fun activities. In short, it is to help everyone in many ways in life and study. Generally speaking, the people in the small class are very good, while our small class Guo is very good. If you don't understand, you can consult a small class. I hope it helps you.
