Please tell me about important weightage topics
Hello Preeti .
I think you are talking about jee mains so in each subject I am telling you separately.
In maths topics which are having more weight is are integration differentiation trigonometry probability relation and function sets.
In chemistry organic chemistry complete have 50% at least so it should be covered completely inorganic chemistry is easy it should be mind game it should be remembered so organic chemistry is much important. I suggest you should leave physical chemistry.
In physics magnetization force friction electromagnetic induction Newton's laws of motion Coulomb's law Doppler Effect reflection refraction modern physics rotation polarisation of light prism are important.
Thank you.
