Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Basic of thermodynamics is required like what is component?what is phase ? what are the variables taken into consideration while considering components and also the( temperature pressure ). all the process like isothermal, adiabatic,isobaric etc. also you have to know the State function and path function more complicated derivation and formula not required . Phase rule formula you have to know properly and also the degree of freedom concept.... Jam student it's enough and don't go for ternary (3 component system ) go for phase rule related problems
