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 Quantum mechanics, Schrodinger equation and its solution for 1-D, 2-D and 3-D box, Solution of 1 dimensional harmonic oscillator , Reflection and transmission coefficient at a step potential and calculation of expectation value are most scoring sub-topics. Uncertainty principle, Pauli-exclusion principle are least scoring. But I want to suggest you that prepare for every topics.
