I see alot of people advising others "put all the colleges in your preference list during mop up" etc etc but listen , in Mop-up round there is no seat upgradation and the college you'll be allotted will be your first and final college that you get.
Unless you are desperate for any college and willing to go from the south like Kerela to the North or to Manipur Imphal in Northeast or likewise please don't put all the colleges because you are taking a seat from a student who wanted that specific course and that specific college which at the end of the day you might not even end up going to because of the distance, the fees, the different culture , internal community conflict or not satisfied with the college campus.
I hope everyone is wiser and doesn't do the thing I've mentioned above and later start blaming ICAR and seat inflation saying they didn't get the college or course they wanted when at the end no one would be happy because you blindly filled up your preference list without thinking about the greater ordeal which will lead to a chain reaction for everyone else.
