Hello aspirant

GVPCE provides around 30% of the seats for direct admission out of which half is for NRI quota and the rest management quota.

The donation amount however varies according to the availability of the seats. You need to approach the college directly to know the exact amount.
Generally, the amount you need to pay for management quota id 3 times the actual fee of that particular course though it may vary depending on the availability of seats and demand of the course.

Hope it helps :)
