Hello Shaifali!

Since there is not much time left for IIT JAM exam, your main focus should be on revising the important concepts and also reviewing the previous year question papers. Having said that, IIT JAM papers have proved to be quite unpredictable in some cases. However these topics have been concentrated a lot and should be taken in consideration by any aspirant:-

• Reaction Intermediates

• Solid State

• Gas Theory

• Chemical Equilibrium

• Phase Equilibrium and concept of Phases

• Chemical Kinetics

• Stereochemistry

• Transition Metals

• Bioinorganic Chemistry

• Chemical bonding and different theories

• Shapes of Compounds

• Analytical Chemistry and methods of analysis

• Heterocyclic and aromatic chemistry

If you would have studied these topics earlier, then revising them and analysing the previous year papers would be beneficial for your final preparation.
