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.

dear, proof is not important, just remember the formula.. but I suggest u that once go through it.. bcz sometimes juniors would ask, and think if u will not be able to give them ans ,this is bad in ur part.. so always try to go through the proof also, only once not more than... and formulas are necessary, they will help u exam... best regards .
thanx
