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 necessary that we have to apply limit to both function at same time

by book and by experience, for example let sinx/x as limit x tends to 0 now if you take limit of just sinx first then you get 0 and but you know answer is 1 so you have to tend limit simultaneously
