Very reliable. I'm just educating with a tiger book. I think it is very reliable, because the question bank inside is almost all original questions. My senior sister bought it. The disadvantage is that the quality of video analysis is not very good, and the teacher doesn't understand it very well. Obviously, many shortcut keys can be operated, and the teacher will be very troublesome. Fortunately, the problem inside is almost the original question, and I forgive its shortcomings.

Take the computer level 2 exam in 2020. When preparing for the exam, you must brush more questions, preferably every day, and brush the questions in the question bank as many times as possible. If you only brush it once, you won't remember it at all. At first, I can only follow the video and text analysis step by step, but I don't know which functional area to click when I don't watch the analysis. It should also be noted that to download the software version needed for the exam, the location and function of the ribbon of different versions are different.

Computer Grade II is divided into four grades, with 0~59 as "failing", 60~79 as "passing", 80~89 as "good" and 90~ 100 as "excellent". The certificate will not indicate the results, but only the level of the test results.

Multiple-choice questions are the beginning of the second-level computer examination. It is difficult to get points, and only one question can be scored, so you can give up the usual choice of multiple-choice questions and rely on them during the examination. The key point is the operation problem, which is difficult and has a high score. If you understand the operation problem, there won't be much problem in the exam. Don't be nervous and calm down during the exam. When you encounter a problem that you can't do, do it first, and then do it if you can't.
