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.

I think you can skip this topic because Quantum Mechanics is not a core subject in IIT JAM exam it is a mixture of many subjects like (Nuclear, Quantum and Atomic Physics) which we called Modern Physics. So the amount of marks it contains is very less. But for MSc enterance exams or Jest, NET, Gate exam Quantum is very very very important.
