Hii,It actually depends on your rank and that year result. The donations fees may also vary with demand and supply for each year.

For Computer & IT it will be slightly higher than other branches.Anyone can't actually predict its exact amount as it totally depends on the people & demand for a seat. The general rule is, better your rank is, lesser you will pay as donation. Your fees varies in general from 3 to 7 lacs depend on branch that you want. Remember that your tuition and hostel fees will be extra than this

So, yes if you are thinking of taking admission in VIT, then YES you can take but wait for the counselling round to end. This whole process starts after that
