Dear aspirant,

As per the previous years cut offs generally the cut off for sc category students stay between 54-56 percentile. That is the minimum percentile required to qualify for jee advanced but to get into nits you need much higher percentile. As per my view 80 percentile is atleast needed to get into a good nit like jamshedpur,Silchar, durgapur, hamirpur.

In lower nits like Mizoram, Arunachal Pradesh, Meghalaya,Srinagar lower percentile can also fetch you these colleges.
