Personally, I think physics is more difficult. Mathematics is the foundation of science and engineering. Without mathematics as the foundation, physics is difficult to learn well, and many physical problems need mathematical formulas to solve. Therefore, good mathematics is not necessarily good, and good physics mathematics is generally not too bad, poor mathematics, poor physics, poor physics and poor mathematics. In short, the two complement each other and are inseparable. People who can learn physics and mathematics well generally have higher IQ.
