should I focus on chem or maths?

my physics is strong.

maths is like almost 0, got 3 marks this time wo bhi due to bonus usse pehle -1 tha.

In chem i got 30 marks, physical chem ho jaati hai, inorganic bhe ek had tak hi hoti hai, zyada yaad nahi hoti, aur organic toh almost nil aati hai.

I can improve in both chem and maths with regular padhai but which should I focus on and how?
