Hello, the third-level network technology of the National Computer Rank Examination is a relatively easy subject to pass at this level. If you want to obtain the certificate of network technology level 3 through self-study, there should be no problem. I don't know if you are a computer major. If not, don't worry. First of all, you need to buy the three-level network technology textbooks published by the Higher Education Press in 2008 authorized by the Examination Center of the Ministry of Education. After getting the textbook, there are learning points and assessment knowledge points at the beginning of each chapter. This knowledge is very important, and there is an exam outline at the end of the book. Read books around these knowledge points and thoroughly understand the contents related to these knowledge points. You'd better learn them by heart. Of course, you are not required to memorize the whole book. Don't swallow the dates, because these knowledge points will be reflected in the exam. Whether it is multiple-choice questions or fill-in-the-blank questions, almost every chapter is more or less focused, so we should review the whole book system comprehensively. In addition, it is best to buy a set of three-level network technical standard prediction questions for the National Computer Rank Examination, test the knowledge you have reviewed, find out which knowledge points are not solid, and review by memory against books, so that the written test will get twice the result with half the effort. Besides, the computer test mainly looks at Nankai 100 questions, because these questions are the essence of the test, and generally more than 80% are the original questions of the test. I don't know how your C foundation is. If so, I suggest you recite the question hard. There are several types of questions, each of which is similar, and only recites the essence. You can buy the simulation test system published by Shanghai Jebsen, test your own back questions first and find your own problems. In short, you can pass as long as you work hard.
