I never think that learning physical chemistry well necessarily means being good at math. Our teacher used to say that physicists should be mathematicians first, which I don't deny. But for middle school mathematics and physics, learning mathematics well has nothing to do with learning physics well. The physics and chemistry in middle school is very simple, and you don't need rigorous mathematical thinking. You can learn physics and chemistry well without being particularly good at mathematics. Personally, if you are not good at math, it is because the algebra part is poor, but the geometry is better? No matter in junior high school or senior high school, algebra accounts for a larger proportion than geometry, which tests thinking ability more.
