Hello Harman,

There is always a state of dilemma for focusing on numerous topics rather than wasting time on less important topics. Chapter wise weightage helps the candidate in categorizing the syllabus into important ones and not important ones. So chapter wise weightage is as given below :-

• Physics

1. Physical World and Measurements - 2%
2. Kinematics-3%
3. Laws of Motion-3%
4. Work, Energy and Power-4%
5. Motion of System of Particles and Rigid Body-5%
6. Gravitation-2%
7. Properties of Bulk Matter-3%
8. Thermodynamics-9%
9. Behaviour of Perfect Gas and Kinetic Theory-3%
10. Oscillation and Waves-3%
11. Electrostatics-9%
12. Current Electricity-8%
13. Magnetism-5%
14. Electromagnetic Induction and Alternating Current-8%
15. Electromagnetic waves-5%
16. Optics-10%
17. Dual Nature of Matter and Radiation-6%
18. Atoms and Nuclei-3%
19. Electronic Devices-9%
