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.

S.R. Ranganathan's faceted Colon Classification (CC) is extremely detailed, precise, and informative, as is the book number system he made to go with it. In his Colon Classification (6th ed.) (Ranganathan 1964) he defined these terms:
[L][F][Y][A].[V]-[S];[C]:Cr[Cr#]
[L] = language number (can be left out)
[F] = form number (can be left out)
[Y] = year (the most important; comes from a table: e.g. N = 1900-1999,
P = 2000-2099)
[A] = accession part of year number (if more than one book from the same year)
[V] = volume number
[S] = supplement number
[C] = copy number
Cr = g indicates a volume of criticism
[Cr #] = accession part of criticism indicator
