Sorry dear, It is very difficult to get DTU under PMSSS with 91% marks in class 12th whether you do it from CBSE or JK board. The competition is very tough for it and most of the students fill this college in their choice filling .
I gaurantee you that you can get better colleges for engineering with this score so dont get motivated and just try looking for some best colleges under this rank.
You can also look some top colleges under PMSSS from here.
