Hello aspirant, hope you are doing good.

I'm extremely sorry to say that with your percentile i.e 64.56 , which is approximately ranked more than 1,00,000 , it's not really possible to get a seat in most of the branches in CBIT , for BC B category. But don't be disheartened, you still have lots and lots of options available to you, that you can choose , to know about all the colleges you can get in with your rank, you can get it here:
