If your family income is less than 1 lakh, then you will get a 100% waiver in tuition fees (which is 1 lakh rupees), and if your family income is between 1 to 5 lakh, then you will be reimburses 2/3rd of your tuition fee.
However, in any case you will have to give hostel and mess fees which is as follows:
Mess Caution Money (One Time, Refundable): Rs.1,000
Hostel Seat Rent (per Semester): Rs.2,000
Electricity & Water charges (per Semester): Rs.3,000
Other fees (per Semester): Rs.6,050
Mess Advance (per Semester): Rs.22,000
Total (Hostel and Mess combined): Rs.34,050
Hope I have answered your question. All the best!
