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.

Boyested for analog and malvino for digital .. these books are so good.. boysterd is the best book you can say... complete theory with satisfication. I only want to say you that follow only one book but it must be standard book and try to complete each topic of jam, don't go through so many books ,it confuses you.. okay dear follow one and do as much as question you can, and ask to us, we are here for you .. good luck ...
