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.

you should learn continuity and differentiability for one variable and two variable both. and my another suggestion about study of real analysis is that try to follow the chain of topics because in real analysis every topic is related to its previous topics..like differentiability related to limit and continuity....so first try to follow the sequence of topics....or you can start new topic after a brief introduction of previous topic
