Hello, 

As you have mentioned that your jee mains ranks is 30224 which indeed is not that bad and you too fall under obc category and hold the Domicile of Andhra pradesh... So, if we over the whole scenario, then you have decent chances to get a seat in any of the NITs or IIITs in the csab special round.. In this round the vacant seats for the NITs, IIITs and GFITs are filled and the cutoff goes somewhat high (rankwise).... Q

Now, just hope for the best and attend the counselling... 

Wish you all the best!!!!

I hope this would help you. For further queries please feel free to write me down in the comment box.
