Hello Aspirant,

To be honest if you don't have even the basic concepts of the subjects then it's very difficult to crack jee mains because it needs years of dedication to crack jee mains .

So I would recommend you to focus on the easy kill topics from all the subjects to ensure that you atleast get this much marks if it came from those chapters .

Chapters like chemistry in everyday life, polymers , biomolecules, 3D vector geometry, matrices and Determinants, Electrostatics, current electricity are scoring.
