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.

the basic law is when we can't figure out what to do start with basic defination.like here i used U=U(T,V). Then I opened them up and put them in the form which I can open and then rest is all maths . I would also like to urge to learn some important equations in thermodynamics which turn very useful in exam and we don't have to derive them there ,saving our time like here I used energy equation ,which can be derived by dif. of TdS equation in V and then using Maxwell relation , feel free to ask doubts .
