University classes are not just big classes. You may often have large classes, and of course there will be small classes. For example, if you take a professional class, it must be you. The small class next to your class is a big class because there are many colleges in this school, and students from different colleges take this course. Courses such as ideological training or politics, such as real-time politics or English, can only be used in small classes. Moreover, this kind of large class only spreads a theory to you and makes you understand something, not that you have really learned anything. For example, when going public, a large class should be able to be about 500 students, with teachers. What happened in some countries recently is just to let you know, not to say how profound your research is. Of course, we must focus on these big classes. Although the teachers in these large classes are not too strict about the test scores, we should also correct our attitude, although this may not affect our future study. However, we should also listen carefully. At the very least, we should respect our teachers and ourselves. The money our parents gave us allowed us to go to college. We didn't attend class every day, and we didn't concentrate on smuggling. Does that make sense? Therefore, although it is a big class, it is better to take notes and listen to the class well, so as to be worthy of our college students' identity. Moreover, people are very popular in such a large class. We should try to sit forward so as to concentrate on the class.
