Hello !
First of all a candidate is offered admission on the basis of rank and not percentile. But from the results I believe the rank would be more than 2 lakh . In Bihar engineering college 50% seats are reserved for general and 12% for OBC . And with this rank it would be quite difficult to get into Bihar engineering college. And any other government college . But you can still hope . You will definitely get great private colleges .
Note- Bihar engineering college reservation is only for Bihar residents .
Hope this helps
All the best.
