what should i do after bba .should i take 1 year drop.or take master in foreign trade 2 year full tym course

If you have chance to join masters than why are you thinking about a gap.

Dont drop better do some job if you are not getting any good college. as in MBA Always Experienced Candidates are preferred. or if you are getting admission in master in foreign trade then you can also take admission in this if your Getting good college.
