Hello sachin

With this percentile it will be not possible for you to get admission in computer science branch of DTU .

Because with this percentile your approximately rank will be more tha. 1.2 lakhs ( may increase depend upon april exam and other students).

As DTU is one the good college and competition is high so you have to secure rank under 3000 ( for outside delhi ) 

And under 8-9 thousand ( for delhi region quota).

So try to score atleast 99.8 -100 percentile marks.

Good luck.
