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.

Only one book can't cover all the physical as well organic parts because in either spectroscopy book aims are different. Physical spectroscopy book aims quantum based understanding whilst organic spectroscopy aims typically interpretation of the molecules. So my suggestion is for physical go for Banwel and for organic go for Silverstein (if you are in M.Sc). Kindly accept my answer
