Hello candidate,

In the Neet sample paper if you consider of topics such as gravitation and States of matter here are some of the key topics which you must practice in order to solve questions from these aspects.

In gravitation first of all you have to remember all the three laws of Kepler motion, derivation and calculation of acceleration due to gravity and its relation with mass and spring balance. In states of matter, you have to go through topics such as amorphous and true solids, cubic arrangement of different molecules, Bose Einstein condensate, Plasma, etc.

Hope you found it helpful!!
