If he is a resident of Delhi then he might get admission there because there is some percentage of quota for inside Delhi students, but for the detailed information, you can go to the JAC Delhi official site.

Hello Aryan,
I am sorry to say, but according to the lateral entry brochure, DTU does not provide admission for CSE branch through lateral entry.

Well you have cleared your boards exam with 77% but your JEE Mains marks are very low. Having SC category quota might help you to get a college for civil engineering.

Hello dear,
If you want to get admitted into NSIT then you must have appeared for JEE Mains and secure a good rank in JEE Mains too. After getting a good rank in JEE Mains, you have to fill a separate form for counselling JAC Delhi. In order to take admission in NSIT, you have to appear for JEE Mains then you have to participate in JAC Counselling. This year cut-off rank for All India level is 4867. You need to score above 60% aggregate in PCM.

Hello dear,
I am attaching a link of JEE College Predictor where you can find the best college you can get through your rank in JEE:

Though with this marks, getting into DTU is difficult. Try appearing for their own exam. Moreover, suggesting you to compromise with the core branches with the name of your college will not be a good decision,

Yes, you can apply for JAC counselling.
All the best.
