I study applied physics, and I am next to applied mathematics. Both of them belong to science and are relatively theoretical subjects. It's really boring to learn, but I think if you like math very much, I mean very much, you can apply for applied math and specialize in it in the future. But if you think that mathematics and physics are like that, then I advise you to apply for applied physics, which has high requirements for mathematics and is much wider than the scope of applied mathematics. There are still many choices for the postgraduate entrance examination, and it is easier to take the postgraduate entrance examination for electronic communication. Moreover, you will have a solid foundation when you study applied physics, and you will have certain advantages for the postgraduate entrance examination ~ ~ ~ If you take a double degree, different universities are different, some schools can and some schools can't ~ ~
