After B.Com in management which line should i select for further studies M.Com or MBA ?

MBA is very costly now a days with comparatively very low returns and struggling career (if not from reputed colleges). After 3-4 years you will end up paying huge fees to college with a shity job in hand. Better choose some professional courses if you academics is good or even if you can work hard.

sir rather than traditional courses I suggest you to go for professional studies like icwai, CFA, ACCA these help you to good job n money to

Dont go for MCom since the scope is very less doing MBA will open up many sectors for you
