What are the chances of vips and agreesen 

There are no minimum marks are required to get admission in the colleges under ipucet.The admission to various colleges are done on the basis of online counselling. As to get a good college your rank have to be under 500. You can also contact to colleges in which do you want admission for the closing rank of the colleges. So there may be a little chance for you to get into these colleges as some students  will go to other colleges or simply get out from this counselling. Wait for the counseling.
Hope it helps.
Thanks.
