Hi Manish,
The course selection depends upon your interest and career goals. If you want to enter into management field then go for PGDM and if you are interested in science then go for M.Sc. Both the fields are good.

MBA and M.Sc both are separate courses. One offers you a generalist management degree whereas the other offers you a specialist Masters. Your choice would depend a lot on your interest areas and career aspirations. If you are keen on doing research / technical /teaching / scientist / manufacturing / quality role then go for M.Sc and if you are keen on sales / marketing / operations / customer service then pursue MBA.
