Hi Makalasailakshmipriya,

you have to give more time on :

1)  units and dimensions and measurement. 

2)  rotational dynamics 

3)  work power and energy 

4) surface tension and viscosity 

5) alternating current and emi

6) superposition of waves and Doppler effect

7) transmission of heat and thermodynamics

8) RC circuits and Kirchhoff law , nodal plane analysis

9) Gauss law for finding electric field

10) nuclear and atomic physics .

Hope you find your answer.
