Mathematics and physics are not absolutely good, but more suitable for teaching (not to discourage you, unless these two subjects are engaged in full-time research, other majors really don't have much demand, at least it is harder to find a job than other majors, of course, if you are admitted to a good university, you will ignore me). Computers are relatively suitable for more jobs and have more room for development, but the problem is that there are too many computer majors now, and the supply almost exceeds the demand (same as above, please ignore it if you take the exam). In short, there is no best major, only the most suitable one. Personally, I suggest learning computer. As long as you work hard, dead trees can meet spring and be practical, and finding a job is Mao Mao rain. (Actually, I mainly heard from the teacher that I was tired of studying physics and mathematics, and I didn't dare to get sick at all. I am afraid that if I miss class, I will not understand. Of course, the final choice is up to you. I hope you can choose the major that suits you best.
