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.

entropy at equilibrium of an isolated system is always MAXIMUM...hence S=K ln omega implies that omega also need to be MAXIMUM..

Well this is a very elemantary yet elegant relation in Physics. This relation is basically a manifestation of Nernst heat theorem, which you can check over the internet or you can read any standard text book of thermodynamics or statistical mechanics. But the main point I would like to state that entrooy is a measure of disorder of a system. Equilibrium happens to be the most disordered state a system can have and thus entropy becomes maximum at equilibrium. So we can say that equilibrium is the most desired or preferred states among all the states a system can posses. This suggest that there must be an inherent relation between the thermodynamic probability of the system and its entropy. This may feel a little round ,but the bottom line is a system wants to posses a state which has maximum number of accessible states and surprisingly equilibrium states satisfy that property with the entropy being maximum.
