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.

according to me eduncle sheet is sufficient but for higher chances for selection and for interview purpose you read some standard books which you can easily Google(this do when you have time). for more related to iit jam books you can buy trajectory education books
since day by day competition is harder and harder. so as much you read,study you have high probability for selection
you can purchase samvedna publication books
Yes sir you are correct the toughness of exam depends on the applicants and so many students prepare for this examination so I have to be better than other. TQ sir
