Can I get admission in Delhi for B.Tech?

Nearly impossible to get admission now because all the admission proceedings have ended. But you can try in some private ones which are situated on the outskirts of Delhi. They intake of students is till mid September. Some of the institutes includes Manav Rachna, Galgotia and Amity.

Yes it is possible in Delhi but you would not get admission in any reputed college or university because it's too late to apply.
