Dear Aspirant 

First of all Congratulating you on your nice performance but I feel sorry to inform you that based on your rank in obc category it is very difficult for you to get a seat in government college like nits. If you were to take my opinion then I would suggest you to wait till last round and the same time keep looking for the another college where you can take admission. 

Good luck for your future :) 

Feel free to ask if you have any further queries.
