The problem you are facing has been faced previously by many of the students in India. The lack of proper knowledge about loan schemes in India has always led people to believe that collateral is the only option they have to get loan from any bank.
So here's the answer for you and many others who are looking for the same.
It is regulatory duty for a bank in India to sanction a collateral-free loan for amount upto Rs. 7.5 Lacs. If you are in need of loan for even more than Rs.Seven and Half Lakhs, only then you can approach some of the Non Banking Finance Corporations, also known as NBFC. NBFCs provide loans without taking any kind of collaterals up to Rs. 50 lacs. But there is one downside too, as the interest rates that of NBFCs are a little bit higher comparing them to public as well as private banks. The lowest interest rates are found in the public banks only.
I had previously approached an NBFC when I needed to give fee for my MBA. They assisted me with a good quality of service during the full procedure. Many NBFCs provides education loans as well as grants and scholarships too.
So, don't worry if you are in need of money for continuing your further education. There are still many choices open for you. Just go and do your best
