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.

there is no such certain books.... you may find 1 or 2 question from some standard books like rudin, Bartley, dumit footebooks. Still these books contain many numericals...hence it is better to do previous year papers. Sometimes a few questions get repeated from past years and paper pattern and the question types are always similar. If you can make good hold on last 5-6 year papers, you will definitely do much better. Do mock tests also. That will boost your confidence and help you to selecting questions in real exams. Best regards.
