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.

Special theory of relativity, vectors(algebra and calculus both),electrostats, with emphasis on polarization,ampere and biot savart's law,poynting vector and em Waves in media, moment of inertia and torque, (1 question for sure),kinematics n Dynamics in spherical, cylindrical and polsr coordinates, entropy, maxwells thermodynamic relations,(easy problems and confirm question)polarization of light(very important),diffraction gratings n absent order problems, digital electronics, especially combination of Gates and Boolean algebra (asked every year),Bjt and op amps(mostly one problem from bjt n one from op amps comes every year), clippers and clampers(Asked in every exam like jam,jest,tifr,hcu),matrices(definitely one question every year), group phase velocities n Doppler effect(mostly 1 question every year),Fourier series and Taylor expansion (1 question), stability analysis and stable equilibrium points (Definitely one problem every year, don't leave this topics.
from where should I practice ... problems for these topics ?
Firstly you should go for old question paper's of IIT ,From there you will get an idea of the level of questions which type of levels are set for the question paper.,
