Hope this helps!

Currently, scope of MBA is wider but slowly industry has started paying good salaries to technologist also

You can try for an elite national college. You'll land up getting clearance for a loan. most people in India go for further education based on loans. Or if you try for foreign university, you can try for scholarships as well.
