Doubt regarding theory marks- division

My main focus is on Physics, Chem, Bio and English. For Maths, I just wanna get like 45-50 in theory. So in this table that they’ve mentioned the weightage, they’ve mentioned marks too right along with chapters. So in the qn paper, let’s say Coordinate Geometry, will there be 15 marks worth qns from that chapter? And likewise for other chapters too? Or will it differ?
