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.

Sure but I would suggest you to buy eduncle notes as they are very detailed and also help you to get grasp of the concepts. Also please suggest a specific topic for which you need help with.
