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.

while calculating lhl f(0-h) there is only this term so we tend our limit but while calculating Lhd f(0-h) is divided by h so we can't directly put limiting value of f(0-h). we have to calculate f(0-h)-f(0)/h together
