Hi fazal ,
I regret to inform you that with such a low score its difficult for you to get admission into any prestigious college of engineering like nits or iiits.
As nits or iiits are one of the most sought after college in feild of engineering so they have high cutoffs for the candidates to get admission.
Either you take part in any other councelling process or take admission into any reputed private institutes with your desired branch.

Hope it helps!!!

Well as you are saying that you have got 42000 rank in obc and 105000 in general category . Then you must have seen what was the scenario of different nit. I guess that you don't want to join lower nit but i am sorry to say that with this rnk you ain't gettng good nit .But ou may gget lower rank in some medium nit or you will get a seat in lower nit.
