It depends on various facets - your category, Home state, Branch you prefer.

But when your intention is just to enter the college without any preferred branch, then your category rank should be at least

General      HS - 120138; OS - 24423

OBC-NCL    OS - 7626

SC               HS - 67957; OS - 4395

ST                HS - 12105  ; OS - 2088

Here HS, OS  refers to Home state, Other states respectively.

And the above-given data are based on the previous year seat allotment. It may vary this time.

All the best..!!
