Hello dear student !

You should have mentioned your category also, so that answering your query more property would be easy. Meanwhile, Pandit Deendayal petroleum University, Gujarat is quite nice University.  From previous years's cut offs, for unreserved category , rank of around 18-25k is needed to get into PDPU which is equivalent to 97-98 percentile to get a seat. So with 75 percentile in mains, it is almost impossible to get a seat in PDPU.

Hope this will help you!
