You cannot get any NIT, IIT or GFTI with your rank. 

Better, do not go for JoSAA councilling. If you want to join any govt. college, then better take a drop and crack JEE with a good rank next year. 

If you are not willing to take a drop, then you can apply for some private colleges. Give entrance test of those colleges and get selected. 

All the best!!!

You can go for private college but chances are low there also.

Hope it helps
