Hello Aspirant,

According to your percentile your approximate rank would be near around 42,000-45, 000 and on the basis of this rank it is little bit hard to get Mechanical branch in NIT Durgapur but as you belongs to OBC and you are female so there are high chances that you might get seat in your required branch which is Mechanical. Note that the above prediction is made according to previous year's cut-off because this year's cut-off has not been released yet and cut-offs are bound to change every year depending upon various factors.

You can check previous years cut-off from the link given below :-

I hope this information cleared your doubts.

Good Luck!!
