Dear aspirant,

It is a bit difficult to predict exact how much marks would be required to get a good nit like jamshedpur, mnit allahabad, Rourkela,jalandhar,surathkal,Trichy. But as per your marks that is 120 on a general basis , it should be around 95.5 percentile but it can vary depending upon the difficulty of the paper , quality of the candidates in that particular shift, vacancy of the seats.

For an EWS candidate atleast 140+ would be a safer side to be.
