Computers are divided into VF and C languages. If I want to choose one of them, then I am a candidate in 2009, and I chose VF. Then let me introduce VF to you. First, the first part of the test paper is a single choice, which will give you some basic knowledge of computer software and hardware and some information about computer viruses. I suggest you buy a basic computer exercise and do it yourself. It should be enough. Then, choose multiple-choice questions, many of which are basic computer questions. What is more difficult is programming. It will test some SQL languages and give you an error correction program (usually only one error). Fill in the blanks is also related to programming. I suggest you go to Shu Ren training class in Shenyang, where they teach well. Many candidates in previous years were admitted there. You can try.
