MBA/PGDM

BIIB is a better option as brand name matters in MBA. Balaji is much better known than Indus Business School. In my view, BIIB is a better option.

If you do not want to make career in the field of Science after B.Sc CBZ then MBA is a very good career switch option. Currently India is on growth path, there are good opportunities for job in corporate world for MBA graduates. You may refer to following link for list of top MBA BSchools in India:

If you do MBA or PGDM from top 50 BSchool, probability of getting a good job is very high.

Among the two, National School of Business is better option. Its ranked better than BIMS and average package is also better. Do you have only these two in options or any other?

Dear Adil,
MBA and M.Tech are post graduate courses, obviously the value is more than B.Tech. After doing such course, you will become master in that particular field.
