Do physics postgraduates choose information and computer science or mathematics and applied mathematics? What should graduate students do when they study computer science and technology? or

This is actually possible, because this science major can only represent your undergraduate stage. Once you graduate and want to take the postgraduate exam, you can choose your own direction or major. Once your postgraduate major has little to do with your undergraduate course, there is a term called "cross-examination". Generally speaking, it is relatively easy for science and engineering to cross-examine humanities and social sciences, but it is more difficult to cross-examine literature. Because many science and engineering courses will involve advanced mathematics and related professional knowledge, you must deal with your opponent who has studied this major for four years in a relatively short time (usually half a year), and the difficulty and pressure can be imagined.

Fortunately, the landlord said that he studied mathematics. Personally, I think mathematics is really a "omnipotent" major, because many science, engineering, economics and even social sciences need mathematics knowledge in certain directions. So you can choose a wide range of ways, you can continue to study mathematics, you can also transfer to graduate students in physics, computer science and technology, and economics. Your tutor will be very happy to know that you will study mathematics as an undergraduate, so it is more or less necessary to do research. When you choose a lot, you can ask yourself which one you like better or which one you are more interested in. Interest is the best teacher. You must be interested in coping with the motivation of constantly studying the life of monks.

Note: Although it is relatively easy to take the math cross-exam in theory, many details should be paid attention to, such as: 1 Institutions or research institutes (hereinafter referred to as institutions) say that as long as you are a student of a certain major and related majors, if you don't belong to it, you'd better ask the research and recruitment office before the exam. 2. Although there are no professional restrictions in some colleges and universities, non-professional students must be required to take several basic professional courses. If you are interested in those professional basic courses,

In a word, cross-examination is feasible, but it also has risks. You must balance your interests with your own reality, and comprehensively choose the major of graduate students.

Finally, I wish the landlord progress in study, success in postgraduate entrance examination and happiness in life. If you have any questions, you can ask me. If you think you can, you will be ruined! Ha ha!
