Hello Vishal 

This is an unexpected questions because it is difficult to end this reservation and even if it ended it will take time to do all the things .

Assume that it get ended ; government will issued notice of the implementation regarding date or even exam conducting committee also analysis it and provide information regarding that it will implement in 2020 or not and accordingly all the procedure and cut offs will be decided.

Case 1 : it is terminated in 2020 ( no reservations ) than cut offs will be equal for each one .

Case 2 : it is not terminated in 2020 admission process ( means it is being implemented after this 2020 session ) ; than all the things will be happen same as it is still happened in previous years .

I think you got it.

Good luck
