Jee mains try to cover all topics while advance has heavy weightage for following topics:-
Physics:- Electrostatics and related topics, magnetism and related topics, modern physics and thermodynamics
Chemistry:- s,p block, coordination, chemical bonding, atomic structure, thermodynamics, electrochemistry, ktg, ideal gases, equilibrium, isomerism, goc, salt analysis.
There are other topic as well but their weightage varies. Like there were times when 50℅ paper of physics came from mechanics and there were times when organic questions were above 50℅, similarly conic was major few times in mathematics.
