The second semester of this year is unknown. I heard a lot of old senior brothers and sisters say that the third year is a good time to skip the course. If you are not interested in the course, you cannot skip it. I really think that when I was a junior year, I was confused about finding a job or taking a postgraduate entrance exam. Sometimes I felt that the more I did, the more confused I was and wanted to do everything, but I think it is not good. If you want to find a job, you can read the books you are interested in to improve yourself. If you want to take a postgraduate entrance exam, you will be able to take high education, English, and so on all day. The professional courses are also ruined without knowing it. Our "Computer System Structure" Teacher is the vice president of our college. He is a professional director and has a wealth of knowledge. But in his class, the students felt that he was always talking about topics unrelated to the course, and he was not passionate and always wanted to go to bed. I thought so at the beginning, but I listened to his class seriously yesterday and found that his lectures were so wonderful, he gave us some things in the textbook, and then contacted his practical experience to explain some examples related to the course, I discovered that this course was so wonderful that after more than three years of teaching, I seldom heard the teacher give us so many high-tech things, what we accept is only the content in the textbook, but we are still happy to say that the teacher is good, and I will explain the things in the textbook to us in detail, but let's think again, in addition to the textbooks, what inspiration does the teacher give us? I cannot figure out what my classmates think. Why do male people have the opportunity to contact masters, but they don't think of them? Is this something that people who study computers should do? Do people who study computer science have to be arrogant. Think about how many computer professionals we have learned in school as students. Now there is something to guide us, and we should cherish every opportunity. Otherwise, after four years of college, we will get too little gains. Many people complain about the lack of university mechanics knowledge. But how many other people actually find their reasons? If I don't care about others, I can't take care of it. Take care of myself. The teacher talked about a lot of high technologies, but I don't know the current situation. I feel that I have a lot to learn, but I feel too many things and I don't know where to start learning. I am also a little confused, ah! I have a good time working on it. There are many channels for gaining knowledge, and I will know more about it. I believe I can learn well.
