Hello john,
Yeah, it is absolutely possible. First thing you have to participate in the CSAB special round 2019 to get the best seat with your crl rank. Once you can check the previous year closing ranks for all NITs and IIITs and fill your choices in the special round counciling of CSAB 2019 then you can get seat definitely. If you didn't get any seat in the special round then your 7th round allotted seat will remains with you only. Hope it helps you.
Thank you.
