i have received offer letter from IMT DUBAI for MBA and MANCHESTER UNIVERSITY for Masters in International Business and Management.
i am confused. which course should i choose.

I guess it depends on which continent you'd rather work in. The real question is: are these the best programmes you can get admission to?

yess these are my only options.
continent does not matter much . Mainly i want to know which one is better and i should choose

If continent doesn't matter, then consider the industries you want to work in. Try: How to use LinkedIn to find the best school www.find-mba.com/board/33571
