Yes, there is tution fees remissions only for those,  who are economically weaker section. Any SC or ST candidate is remitted to pay full tution fees.  Any OBC or general candidate with income less than 1lakh is remitted from paying whole thtion fees. And OBC or general  candidate with income between 1lakh and 5 lakh gets the 2/3 remittance of tution fees.

Tution fee is 62500 per semester.
