One is to specialize in mathematics, which requires that mathematics be particularly good. After you are ready to devote yourself to mathematics research, you must have enough interest and patience to study mathematics. The best math major should be Peking University.

But many schools are very good, and there is not much difference between good and bad majors.

The second is the computer direction, which has a bright future in the IT industry. The best schools are Tsinghua and Jiaotong University. Of course, these schools.

The score is very high, there is a Northeastern University, and the computer and software are also good, but the score is not very high. Maybe we can consider it.

You have to figure out what you want to do in graduate school. Most people think that the purpose is to find a good job. In this case, if you can find an ideal job after graduation, you can consider working for a few years first, and it is not too late to go to graduate school when you want to recharge. If you can't find a suitable job temporarily, you might as well consider going to graduate school first.

You should consider your own strength, after all, there will be some conflicts between postgraduate entrance examination and job hunting. If you think you have enough strength, you might as well make preparations and look for a job while taking the postgraduate entrance examination.

Finally, I think the financial strength of the family is also an aspect I should consider. If the economic situation does not allow, it is better to work first.
