I don't think it's necessary, and it's not easy for me to take the second grade. I am from Changsha, Hunan, majoring in accounting. I got 80 points in the computer practice class in the first half of the year, although I can't do the last question. And that practical test is very basic computer knowledge, one is WORD typewriter composition, the other is EXCEL table making and drawing, and the last one is VF, which I don't quite understand. In short, it's relatively simple, so don't worry. Go boldly.
