Hello aspirant,

You asked if you apply in dtu with sc quota you may get a seat or not.

Now, see,

Delhi Technological University (Formerly Delhi College of Engineering)is one of the best technological universities in India. You told that your father is in bsf. So, yes, you are eligible for the defence quota. As you are sc too you may also apply sc quota. As with defence+ sc quota you didn't get a seat, you will not get a seat probably with using only sc quota also. Still you may try.

All the best  !!
