M.Sc

Hi,
Either one can be done which will depend completely on your interest. MBA is ideal if you are opting for a managerial career. But most MBA programs do not admit freshers and work experience is compulsory. MS is research oriented, if you want a research or academic career in your discipline. Admission in MS is also very competitive.

You have many options in front of you. If you have completed your under graduation it gives you a license to practice your profession or get employed in the industry. If you want to pursue higher studies, you could do that as well, which will give you access to additional avenues. The choice is yours.

Hello Gunnu,
Choosing specialisation in Masters is good for those specifically interested in that to pursue research on that field if you aspiring that go for it. Else pursue M.Sc micro for wider opportunities.
