Hello,

Its totally depend upon your rank and the course you want to take admission. For b.tech your rank should be around under 20k, if you are crossing that limit then there is less chance that you will get admission through counseling. For that you need to take admission through management quota and in management  quota they will ask you for the donation.

It totally depends upon the course and the branch you want to take, and the state where you belong, around 6 lacks they will charge you for CSE seat in b.tech, and if you are planning to take admission through management quota the do it fast.

Best of Luck!!!
