Hey dear ,according to your percentile in jee mains your general rank will be in between 70k-80k which is not to get admission in DTU colleges. If you belongs to Delhi then there is chance to get admission, for outside Delhi there is very less chance for DTU.

Hey aspirant, sorry to say but your score is quite low for any of the good engineering colleges in Delhi. But you can get into DTU if you are a Delhi resident. Most of the good colleges in Delhi give a lot of preference to residents of Delhi. It usually doesn't matter whether you are a dropper or not it just affects on no. of attempts remaining.

At 91.136 percentile your rank is about 77 thousand which is calculated by the method released by NTA.

If you're not a resident of Delhi then I will suggest you try to improve your percentile in the coming April Jee mains.

I hope you will be able to score more this time.

Goodluck.
