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.

yes it is enough to your math related questions. but for other subjects you have to study through syllabus.
Only do important part from 11th 12th books as per syllabus for each subject.
