Because it will be related to this thing in the future, and it will be used in circuits, physics and computers. The main thing is to start with the textbook, look at the nature, theorem and formula, and then do the exercises after class well, so as to learn well. Of course, if you want to teach and research, you have to spend more time studying advanced mathematics. In addition, the usual homework must be done well, not casually, you can discuss it with your classmates if you don't know, and never copy it. Otherwise, you will become lazy, just don't go to class in the future, and always feel that you have no time to wait.
Oh, don't think college is fun. In fact, the university really has a lot to learn. You can't just sleep and play all day, so hurry up. I usually study by myself, read some books and do some interesting things. One week, study from Monday to Friday and relax on Saturday and Sunday.
Finally, I wish Xuedi a full college life and rich feelings. . . . .
