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.

this question has no sense. because it depends on you how you are study. if you don't study regularly and not complete home work, assignment,lab,project on time. and don't read what they taught, don't read books what they suggest along with some standard books then m.sc is difficult everywhere for you. otherwise it is easy and has very good journey
