You can avail these reliefs from the college/ banks to pursue your education at NIT Durgapur-
The tuition fee of NIT Durgapur is INR 62,500 per semester for B.Tech students. But if your family income is less than 1 Lakh or you belong to SC/ST category, your tuition fee will be 100% waived. If your family income is between 1 Lakh- 5 Lakh per annum, your tuition fee will be 2/3rd waived.
To get a waiver on your fee, you have to submit an income certificate from competent authorities.
You can take an educational loan from a bank. When you visit the campus during admissions, you will spot people with pamphlets of their banks. Approach them and they will guide you through the entire process. I know some people who teach tuition to local students. This is a great way of earning some money on the side.
I hope this answer helped you and provided some useful guidance.
