Hey aspirant, there is no fixed wieghtage of marks of any chapters in any subject. The pattern of  questions  changes every year. Jee advanced question paper highly qualified examiners. They always try to outwit the question and pattern guessing on the basis of previous year papers. Getting topic of choise is all about luck in jee advanced.

Hello Aspirant
.
For jEE mains and advance the topics like coordinate geometry,integral calculus, limits and continuity has more weightage in math.
For chemistry the topics having more weightage are:-

• Transistion elements and coordinate geometry
• Periodic table and representative elements
• Atomic structure
• Chemical bonding etc.
