Are you asking for MHT CET TFW (T uition Fee Waiver)? If yes, Then Tution Fees Waiver is not based on Exam score, It is based on Family Annual Income which you will require to have less than 6 Lakhs and these seats are S upernumerary.

For Government colleges it is mostly waived but for Unaided Institutes, only a certain amount is waived.

Good Luck!
