You can also take the computer major. Why do you want to change your direction when your computer major is so good? It's not necessary. It doesn't matter if you are not good at math. Can you get 80 points? If you can get 80 points, that's enough. The national line is only over 60 points! There are not many good math, just practice more at ordinary times. There is nothing flashy about taking the postgraduate entrance examination for mathematics, just practice more at ordinary times, don't just watch and don't practice. I just watch too much and practice a little less. I only got 8 1 in the 2007 exam, which is already a high score. Now the score of postgraduate entrance examination is abnormally low, and postgraduate entrance examination is not generally easy. Nanjing University of Posts and Telecommunications and Hangzhou Dianzi University are both good schools, both of which are good at exams and employment. After graduation, you can go to Huawei, ZTE, Noci, A Lang and so on.
