Hello Rahul,

I think class 11th is the backbone of your future studies, but now as you say you waste most of your time then, study thoroughly the topics I mentioning below for particular subject.

(A) Physics

1. Units and measurement, kinematics, laws of motion. (Approx 18 marks)

2. Work, energy and power , motion of system of particles and rigid body (approx 12 marks)

3. Thermodynamics , it's a very important topic for your future studies (approx 7 marks)

4. Ossilation and waves( approx 10 marks)

(B) Maths

1. Sets and Function (approx 23 marks)

2. Algebra, it's the most scoring topic in class 11th maths ( approx 30 marks)

3. Coordinates geometry and statistics and probability, it is interesting and easy topics and you score full marks ( approx 18)

(C) Chemistry

1.chemical bonding, States of matter, chemical thermodynamics and equilibrium (approx 20 marks)

2.organic chemistry,. Hydrocarbons, and environmental chemistry ( approx 15 marks)

3. Structure of atoms, redox reaction, hydrogen (approx 12 marks)

As you ask for important topic with there weightage.... I provide it to you.

But in my opinion you have to go through whole subject once.

Good luck and best wishes for your exam.
