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.

kindly explain Net migration
net migration is how many people came to your country minus how many people leave the country. if total population is 100 ,20 people emigrate from your country and 40 immigrated to your country so net migration would be 40-20 =+20 so now total population would be 100+20=120
