Hi,

Dtu takes admission through jee main merit/rank of candidate.

With 91 percentile your probable rank will be around 10,141. You can  calculate your expected rank by using following formula

100 - your total percentile score is the percentage  of people ahead of you. 112679 are the number of candidates appeared for January exam.

So rank formula is (100 - 91) X 112679 /100.

The cutoff rank for EWS category seat through jee main in Dtu was in the range of rank around 38000 for home state and in around rank 8000 for other state  candidate.

So if you are home category candidate then there are decent chances that you can get a seat and if you are other state candidate then it will be very tough for you to get the seat.

So  I will advice you to give April session exam so to increase your rank.

You can also check the college predictor link below to know which other college you can get with this percentile.

All the best.
