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.

focus on above 60 to get good IIT but my opinion is to cross the Barrier of 80 u will definately get iitb or any old IIT.
I asked this question before JAM... Anyway thanks Sir....
