Good physics means that you have a good scientific thinking. The mathematical calculation involved in high school physics is basically the level from junior high school to high school (except vector and other knowledge), and mathematics needs long-term accumulation of basic skills. High school mathematics knowledge covers a wide range of fields. You may be able to solve problems with a better brain, but sometimes math problems require a lot of math operation skills. In a word, mathematics needs to know more problems than physics. In short, mathematics needs to do more problems and master them in doing them.
