Of course, college students should preview before class. When I first entered the university, I didn't preview before class, and then every time I went to class, I felt that the course was so difficult to understand, so I slowly deserted and finally came down. Therefore, preview before class is of great help to the concentration and quality of class. I watched my classmates in class with relish, so I specifically asked. There are also previews before class. Later, I also tried to preview before class and found that the effect was very good. I can keep up with the teacher's ideas when I attend classes, and it is not as difficult to understand the knowledge points as before.

First of all, after entering the university, college students learn more by self-study. Teachers usually impart knowledge in class. If students don't ask after class, teachers won't care. Therefore, we should try our best to understand every knowledge point spoken by the teacher in class. Pre-class preparation can not only enable us to learn by ourselves in advance, but also list the knowledge points that we don't understand during self-study, so that we can understand the knowledge points that the teacher doesn't know in class more easily.

Secondly, preview can make us understand the content of the class more clearly, so that we can keep up with the rhythm of the teacher's knowledge explanation when the teacher is in class, and pay attention to the class in time when it is important and difficult. If you don't understand anything, you can immediately raise your hand and ask the teacher, so that you are not afraid to miss the teacher's questioning time when you don't understand the key points and difficulties.

Finally, you must sketch pictures before class, not just look at them. When we encounter something we can't do, or something we think is very important, we can sketch it down, so that when the teacher is in class, it will sound easier to combine the knowledge we have previewed in advance. We also need to study by ourselves when we preview. Let's learn simple content, and with the teacher's explanation in class, we will have a deeper understanding of every knowledge point.
