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.

sabia, in net they don't ask you to find tangent inverse of any angle besides some most popular angle (0,90,45,30,60 deg.) so don't worry . If they ask to do so at any questions you simply pass by the question. I don't think they ask such a silly type of questions.
