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.

Inner core is surely more rigid than lower mantle because of the extreme pressure conditions ranging in 250-350 GPa, which is itself explanatory about the solid nature of the inner core. But the velocity of seismic wave(probably here I'm talking about p wave) is less than that of lower mantle(velocity in lower mantle reaches upto 13 km/s while it drops down to 11km/s in inner core.
