Hi Snehasis,

Every chapter is important, but you can target

In maths- coordinate geometry, complex numbers, vectors and probability.. if u want more than include 3d geometry and functions. 

In Chemistry- p-block and coordination compounds, general organic chemistry, isomerism and hydrocarbons(alkanes , alkenes and alkynes), electrochemistry , stoichiometry , solutions , equilibrium and thermodynamics

In physics- Newton laws and friction , electrostatics , current electricity ,magnetic field, electromagnetic induction , heat and thermo (easy scoring topic) , rotational , work and energy

Try to take help from Askiitians online classes, they can help you in these days to prepare
