Hi,

I dont think so. Most probably its kind of a hard deadline. I suppose you should be positive now and wait for CSAB. Many NITs and GFTIs have vacant seats in both Core and Circuital Branches in CSAB.

You should probably target your Home State NIT or New NITs CSAB round. Besides this, BIT Mesra is another good GFTI, where you can be confirmed of a seat in CSAB.

For more information about CSAB round and procedure do follow the link below

Hope this helps.

All the best.
