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.

In series , we mostly use different test like ratio,root,cauchy condensation , comparison tests . Here we can't check convergence just by checking lim(n --> infinty)an . In sequence , we generally/mostly use lim(n->infinity)an for convergence/divergence checking . We can also check convergence/divergence/oscillation of sequence/series by finding limit superior/inferior. Solve/practice question of sequence/series that will help in learning .
