Hi spoorthi ,
I regret to inform you that with such a low score you cannot 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.
Even in lower nits like northeast nits the closing cutoff for obc category student goes maximum upto 15k to 16k . Either you take part in any other councelling process or take admission into any reputed private institutes.

Hope it helps!!!
