Work, Energy and Power take 4%, Atoms and nuclei, Oscillation and Waves, Properties of Bulk Matter, Laws of Motion and Kinematics share 3% and the rest of the topics carry 2% weightage.

In Chemistry, Coordination points get 9% of weightage. Thermodynamics takes the 8% and Equilibrium takes the 6% weightage slots respectively. Chemical Bonding and Organic structure carries the 5% weightage slot and rest of the topics carry 2-3% weightage in the exam paper.
