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.

I suggest you to read the real analysis book by S C Malik. or for more basics you can refer SK Mappa Or N P Bali. Even book by Shanti Narayan is very good to clear these basics. Read concepts and solve numericals based on these topics...for numericals ,you may refer book of Bartley... You don't have to read all these books ,just read these topics from any one or max 2 books mentioned above. Yeah, practice as much as you can. You can find some handwritten notes on google. That may also help you.
