Since the first half of this year, CET-4 has cancelled the advantage test.
Buy another book, for example; In addition, you should be able to pass the test questions over the years.
What is the computer level 2 exam? Is it better? It depends on what you took in the exam. It's not that hard. You can pass the exam if you study hard.
What is the computer level 2 exam? Written test and computer! Just buy a simulation!
Do you take the CET-4? The content of CET-4 basically covers the four-year undergraduate course of computer major. The basic contents include computer composition principle, computer operating system, discrete mathematics, database principle, information theory foundation, computer network technology, software engineering, 3-hour competition, full score 100, computer programming. The topic is usually the same and needs C language. The perfect score is 100. The written test and computer operation are passed separately.
The exam syllabus is different every year.
What are the computer level one exams? Level 1 certificates are mainly divided into the following categories:
Level subject/category examination form
First-class Microsoft office computer
First-class computer
First-class WPS office computer
That's all!
What's the second-level VB test for provincial computers? The written test seems to be richer. There are some basic conceptual problems and some attribute operations, which depend on you to remember. The difficulty is programming questions, mostly related to mathematics, mainly the use of test cycles, public * * *, basic knowledge 30 points.
Machine testing is divided into three parts. The theme of the first two parts is very simple, mainly focusing on the application of control element attributes. The third part is more difficult, which is the test of file operation, that is, how to open the file, read the contents of the file into the array, then operate the array according to the requirements of the topic, and then get the final result and put it back in the specified file. The last question may provide you with some compiled programs, or it may not provide you with anything. You must do it yourself.
It's no use talking too much. You should recite more concepts in the written test, mainly the basic knowledge of public affairs. The rest is up to you to get on the computer more, and everything will be solved if you get on the computer more (it is very important to pay attention to strengthening the practice in the document part) ....................................................................................................................................
Vb is very interesting. I suggest you learn some knowledge of api functions.
