Hi Bharath Nanda

I am sorry to say that you cannot get into IIT karagpur or any IIT colleges without qualifying JEE advance exam. But if you have qualified in JEE mains, you may get admission in NIT (31 colleges), IIIT (23 Colleges) and CFTIs (23 colleges) based on your JEE mains rank. There are some universities and colleges accepting JEE main scores.

Regards.
