Compared with other specialized courses, computer specialized courses have many knowledge points and heavy tasks. If my undergraduate foundation is good, it will be of great help to review. For example, I need to look at some knowledge points or algorithms for a long time to understand. Even if I understood it at that time, I will forget it after a while and need to watch it again. As far as the four subjects of postgraduate entrance examination are concerned, I think the skills of the other three subjects are zero except data structure, so as long as you are willing to work hard, you can still get an ideal result. Let me talk about the characteristics of each subject:
I. Data structure
As can be seen from the score, this is a crucial subject. There are two big questions on the test paper, and the score of the second programming question is higher, which seems to be about 14 (I can't remember clearly). These two questions are relatively simple, and it is estimated that the difficulty will be improved in the future. I think my major is to master all kinds of data structures and sorting search algorithms skillfully. I will take time to review regularly, and I will definitely forget and understand. There are relatively few conceptual things in this subject.
Second, the principle of computer composition
As important as data structure, examination is also two big questions, both of which are difficult subjects. Important truths must be understood, with emphasis on understanding, so as to be impressed. For example, I wrote the big command questions in the exam entirely by understanding. There are many knowledge points in the planning group, so I may forget them when I am nervous when I go to the exam. As a reminder, some books may have different definitions of cache group connection. We still follow the understanding written in the textbooks of Grandpa Bai and Tang Shuofei. After all, these two are more authoritative.
Third, the operating system
There are two major questions in the exam, of which the semaphore is the most important. I thought I had to take the exam, and I did. There are many knowledge points in this subject, and many of them have to be memorized. The big questions are relatively simple, which is the guarantee of scoring.
Fourth, computer networks.
There is a big question in this exam, and there are few important big knowledge points. Apart from the IP address, there is nothing troublesome to calculate. Routing table is the key point, and 2009 is a related big issue. Generally speaking, network computing is not difficult, and the examination requirements are relatively low. Some knowledge points in reference books and exercises are biased. At that time, I thought I couldn't pass the exam, so I stopped reading it after reading it once.
In fact, some parts of the four subjects are related. For example, both computer groups and operating systems have chapters on storage, and the calculation of addresses in computer groups is the same as that of computer network IP addresses. You can learn by comparison. If you have a good foundation, you will save a lot of time. Those complicated algorithm principles may be recalled when you look at them, and it will be relatively easy to recite them. If you haven't learned it before, you may not understand it for a long time. Real learning should be based on your own situation, step by step.
When reviewing, we should distinguish between key points and difficulties, and don't dwell too much on unimportant knowledge. From the examination paper, the focus of the investigation is the understanding of the important and difficult points, and there are fewer conceptual things. Do more exercises and ask for a certain amount on the basis of quality. After learning to a certain extent, you can try it yourself. When you start reviewing, you should set yourself a goal of scoring, and decide the degree of review according to the goal. Step by step, keep breaking through, master scientific review methods, and believe that scoring professional courses is not a dream.
