If you are from general category then u cant get admitted in iit karagpur because for that first of all you have to cross the cut off . Followed by its mandatory to clear jee advance. But if you are from obc category then i would say chances are there but still a very less possibility will be there because you may clear jee mains easily but for advance you must also clear jee advance with proper criteria . Last but not the least if you are from sc / st category you have better chances. 

Good luck!
