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.

if any doubt then ask
but in 3 rd qn,alpha square belongs to S4 and e belongs so...
I think there is mistake in 3rd question.. there should be alpha €S4 .
because if there is (alpha )^2 then cardinality of A will be 1
feel free to ask again
