Mid Jee journey

I am in class 11 preparing for jee 2026 through dummy coaching I stated well(being top 5 in a batch of 30 with 150-170) then after some ups and downs(more downs)I have reached 100 marks now I have backlogs like gaseous state,Chemical equilibrium, elasticity and some other topics.I have a very strong point in physics and my maths is shit I practice very less questions I have learnt just formulas and know theory with some major holes but at December end I have been serious with my studies now chemistry is also my strong point but my maths is still shit I just want to know that what should I do to make my maths stronger and how do I get started? (Your opinion matters to me very much)
