I shall tell you what happens!!!
One of my friends secured a rank of about 10k in viteee 2018 and he did not score well enough in jee mains 2018. Assuming he had no other good choice,he went to vit vellore for the counselling procedure on 9th May.
There ,he found that all seats of computer science streams had been occupied,only a stream of cs with biology had vacant seats. On being called inside,the people there asked him what he wanted . He said that it cse was his desire but that al seats had been filled up. One of the men there told him not to worry,if he paid 1 lakh extra,he woyld be given a seat in any stream he wished. They even stressed on the fact that the money should be handed out tre itself.
I do really hope that my friend made up some of this because it is disguating to see such kind of politics in a top engg college.
