Hello anamika,
Yeah, 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. I will provide one link. You can check the previous year closing ranks. Here is the link.

Dear Aspirant

First of all Congratulating you on your nice performance that you deserve such a good college and I would like to tell you that based on your rank in general category and considering the fact that you belong to general category, I would suggest you to must participate in spot round counselling conducted by JoSAA at the end of normal round if you couldn't get any college in normal round. Otherwise till then you can take admission in knit sultanpur.

Good luck for your counselling :)

Feel free to ask if you have any further queries.
