B.Sc

Good question, but the choice of higher studies is purely based on your decision. Higher studies are purely based on also what kind of a job or role or position you are looking out for. As far as an MBA is concerned, if you look ATIT the main role and responsibility is managing the work as well as delegation. But for doing justice to this role, one needs to know the ground rule or the basics of the job. As far as an M.Sc is concerned, mainly it is a research oriented profile. Now the choice is yours. You would have to self-introspect. Whether you are a Research kind of a person or would you prefer to manage the work as well as delegate work.
But if I am to advice you, I would suggest that if you are able to get an answer by your self-introspection then follow it accordingly. But if you are unable to get an answer, it would be good if you could get into a job, realize your potentials and at the same time study the market, their needs and the job opportunities created and then opt for higher studies. As far as managerial role or MBA is concerned, even after introspection, if you feel you fit in with this kind of role, I would recommend, you to wait, fend a job, and take in experiences. Only then will an MBA degree would be helpful. Also please note that with certain M.Sc specialisation an MBA degree would not be helpful. So make a confirmed choice.
