(1) From the perspective of subject difficulty,

Mathematics is the basic subject of science, while physics is the diffraction of mathematics. Mathematics is often called the king of disciplines, because mathematics can solve many things, so physics is definitely not difficult to beat mathematics, because physics is fundamentally studied by mathematics.

(2) From the perspective of professional development.

Mathematics has a wide range of diffraction, which can involve aerospace, national defense security, data and information, energy exploration, artificial intelligence, advanced manufacturing, philosophy and culture, financial bonds and so on. It involves many development directions, but physics has certain limitations. He is a diffraction major in the field of mathematics, with a narrow range of development directions and a narrow range of occupations that can be involved in the future.

(3) From the perspective of developing schools.

According to the schools that carry out the strong foundation program at present, there are 18 colleges and universities offering mathematics majors, and 12 colleges and universities offering physics majors. In terms of quantity, there are more mathematics, and the chances of applying for mathematics major have also increased.

To sum up:

Mathematics is more difficult than physics from three angles. Professional development and school development are better than physics, so if you want to choose between them, I personally think you should choose math major.
