Well, it's hard to say. Generally speaking, mathematics is a tool to solve problems in other disciplines. The study of physics requires not only a good grasp of mathematical knowledge, but also a good understanding of physical processes. So it is difficult to understand physics from this level. Of course, there are many abstract and theoretical things in mathematics. Interest in learning is not as strong as that in physics, which has many interesting experiments and phenomena. In short, the difficulty varies from person to person, and interest should be the best teacher.
