I am from a middle class family and I have recently done my BBA. Can I get any loan or scholarship to pursue MBA abroad?

There are many universities which offers scholarships, your six semesters score ( academics) from reputed University matters lot. Your college will guide you more in this matter.

It depends upon your graduation percentage. Also, you can apply for a scholarship and if you are eligible, you will get one. All the best. Singapore is better for MBA because it is affordable and educational pattern is also good.
